Extinction a worthy election issue

Extinction a worthy election issue

This past week we have seen young people (and their parents, grandparents and other supportive adults) taking to the streets worldwide to protest against government and societal inaction on climate change. They are angry, and they have every right to be. As UN Secretary General Antonio Guterres said at the Youth Climate Summit: “My generation until now has failed to preserve the planet”.

For many, climate change is or should be one of the most important issues in the federal election. After all, we are hearing increasingly desperate calls to action from the scientists monitoring climate change. They see change happening more dramatically and more rapidly than they expected.

But it is not just climate change that we should be worried about; other major global changes are underway at the same time, changes that are as serious as climate change, if not more so. These include depletion of vital resources such as forests, fisheries, fresh water, topsoil and farmlands; widespread pollution, including food chain contamination; declines in the populations of many species and an increased rate of extinctions.

Moreover, these global changes are not distinct from each other, but interact in ways that almost always make things worse. For example, climate change warms the oceans, harming coral reefs that are key ocean nurseries, while CO2 emissions acidify the oceans, which harms reproduction and growth among molluscs and other species. On top of this, over-fishing and habitat changes such as we see around the Northwest and elsewhere are further depleting fish stocks.

Clearing the Amazon to create farmland hastens climate change, destroys habitat and reduces biodiversity, while intensive agriculture and widespread pesticide use further reduces biodiversity. Furthermore some of these pesticides and other persistent organic pollutants bio-accumulate in food chains and disrupt endocrine and immune systems and the brain; they may be contributing to reproductive failure and immune system dysfunction in many species.

The result of all this is that we are triggering a sixth ‘Great extinction’ – the last one, 65 million years ago, saw the end of the dinosaurs. But before we see actual extinctions, we see declines in populations, as a report last week in Science noted: “extinction begins with loss in abundance of individuals that can result in compositional and functional changes of ecosystems”.

That same report noted “a net loss approaching 3 billion birds, or 29% of 1970 abundance” among North American birds. We have seen massive declines in other species, including frogs, insects and fish. Globally, populations of large freshwater animals (fish, reptiles, amphibians and mammals that can reach 30 kg in weight) “declined by 88 percent from 1970 and 2012”, a 2109 report noted, with losses of between 97 and 99 percent in Europe, Asia, and northern Africa.

The Worldwide Fund for Nature (WWF)’s Living Planet Index, which monitors population counts for over 4,000 freshwater, marine and land vertebrates (mammals, birds, fish, reptiles and amphibians) declined 60 percent from 1970 to 2014.

The overall picture was summed up by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) earlier this year: “The average abundance of native species in most major land-based habitats has fallen by at least 20%, mostly since 1900. More than 40% of amphibian species, almost 33% of reef-forming corals and more than a third of all marine mammals are threatened”.

The main culprits, the IPBES reported, are changes in land and sea use; direct exploitation of organisms; climate change; pollution and invasive alien species. A 2019 study on declines in insect species identified much the same set of factors at play: Us, in other words.

We would do well to remember that we too are a species, and that although right now we are more a threatening species than a threatened species, that can change. As the WWF report notes, “biodiversity has been described as the ‘infrastructure’ that supports all life on earth. It is, simply, a prerequisite for our modern, prosperous human society to exist, and to continue to thrive”.

So yes, climate change should be an important issue in this election, but we need to raise our sights and make extinction an election issue too. Ask your candidates if they will declare both a climate and an extinction crisis NOW!

Our health should be an election issue

Our health should be an election issue

Dr. Trevor Hancock

To the extent health is an issue in the federal election, it will be about health care, as usual. Now I am not saying health care is an unimportant issue, but this focus on ‘health care as health’ is wrong for two reasons. First, health care is a provincial responsibility under the Constitution, so the federal government plays no real role in managing Canada’s various provincial and territorial health care systems.

Second, and more important, health is not health care, it is a much bigger issue – and one where the federal government can indeed play a major role. If we really want to improve health care, we must improve health, thus reducing the growing burden of disease and injury the health care system has to handle.

So as we think about the federal election, look at party platforms and promises, and engage with candidates, the question we should be asking is “What will you do to protect and improve the health of Canadians?” Here and in the next few columns I will discuss the policies I believe we should be looking for ro determine whether our political leaders really understand and care about the health of Canadians.

In this I am not alone. The Canadian Public Health Association (CPHA) has identified eight top election issues and has produced an excellent set of resources for citizens and public health professionals, giving easy access to the parties’ platforms and tools to help people engage candidates in their riding (see www.cpha.ca/election-2019)

CPHA’s priorities include such basic determinants of health as income, housing, early child education and climate change. They also focus on the opioid crisis, decriminalization of personal use of psychoactive substances, racism, and not surprisingly, on the funding of public health. To this list, I would add food, transportation and urban development, although the latter, like health care, is within provincial but not federal jurisdiction.

But over and above all of this is the need for a comprehensive and strategic approach to improving the health of Canadians. There was a time, in the 1980s and 1990s, when Canada was a world leader on these issues, but sadly that is no longer the case. As with so much else that is wrong with public policy, it is not lack of knowledge that leads to poor policy choices, but lack of wisdom, lack of a long term perspective and the inability to act in the public interest rather than in the interest of powerful corporate and institutional players.

The first step in making the health of Canadians a priority is to recognize that the Minister of Health is actually largely the Minister of Illness Care, and that it is the Cabinet as a whole, and the Prime Minister or Premier in particular, that is really the ‘Minister of Wellbeing’. Improving the health of Canadians depends more upon the Ministers of food, housing, education, finance, social development, environment and climate change and others than the Minister of health.

The Canadian Senate recognized this in a 2009 report that recommended “A new style of governance: leadership from the top to develop and implement a population health policy at the federal, provincial, territorial and local levels with clear goals and targets and a health perspective to all new policies and programs”.

Specifically, the Senate recommended creating a Cabinet Committee on Population Health (which should be chaired by the Prime Minister/Premier) that would develop and implement a population health policy. This policy would require an assessment of the health impact of policies in all sectors, and a spending review to determine where we would get the biggest health/human development return on our investment.

To this, I would add the creation of an independent Canadian Population Health Officer, reporting to Parliament (not to the government) on the effectiveness of public policy and programs in improving the health of the population.

The report sank like a stone! So if you are concerned with the health of the population and the sustainability of the health care system, you should ask candidates if they will commit to creating a Cabinet Committee on Population Health, displacing economic development as the central focus and instead putting development of human wellbeing at the heart of government.

The price of societal neglect of children

The price of societal neglect of children

Dr. Trevor Hancock

10 September 2019

This is my final column about Tyler, the fictional but prototypical young offender whose story was told in a 2016 Public Safety Canada (PSC) report. Last week I discussed the value of support in the first three years of life to help parents create secure attachment, as well as interventions to reduce the occurrence or reduce the impact of Adverse Childhood Events (ACEs). The latter includes eliminating child poverty – which is always, of course, parental poverty.

Oddly, the PSC report did not include these early interventions, perhaps because they are for all children, while the interventions they reported on are all aimed at children already having problems or involved with the justice system. But nonetheless, for the two interventions described here, the estimated net savings for Tyler were in excess of $1 million. (A third program described in the report seems to be less effective in Canada than in the USA, where it was developed, so is not discussed here.)

The first program is SNAP – Stop Now and Plan, a Canadian program developed by the Child Development Institute in Toronto since 1987 and now recognized internationally. SNAP works with troubled children aged 6 – 12 and their parents and its goal is “to help children to stop and think before they act, and keep them in school and out of trouble”.

Public Safety Canada notes a 2007 study found that “delinquency, major aggression and minor aggression decrease significantly after participation in SNAP”, at a cost of less than $7,000 per participant. SNAP itself reports: “Recent research indicates that 68% of SNAP participants will not have a criminal record by age 19”, and that the return on investment is $7 for every dollar invested in the first year.

So you would think this program would be in place across Canada – and you would be wrong! SNAP’s website describes its plans to expand from the current 20 sites in Canada, of which only 4 are in BC; the Coquitlam and Nechako Lakes –Vanderhoof School Districts and two small community agencies in Vanderhoof and Salmon Arm.

The second program is the Youth Inclusion Program (YIP), which was developed in 2000 by the Youth Justice Board in the UK. It is a neighbourhood-based program that works with adolescents (age 12 – 17) and young adults (18 – 24) and is supported through PSC’s National Crime Prevention Strategy. It aims to create “a safe place where youth can go to learn new skills, take part in activities with others, and receive educational support” in areas where “where there is a strong need to reduce youth crime and antisocial behavior”.

The YIP also works. Two Canadian evaluations between 2010 and 2016 showed that participants reduced their risky behaviours – in one case by 67percent – at an average cost of between $8,500 per participant. But again, there were only 13 sites in Canada, with 3 in BC: Agassiz-Harrison, Smithers and Salmon Arm.

It is important to understand that as with so much else in society, the worst-case stories are the tip of the iceberg, and do not represent the whole picture. For every Tyler, we can be sure that there are many others whose problems were not as obvious or severe, but who nonetheless were problematic. In fact, the chances are that their overall impact on society is greater. The loss to society – not just economic loss, but loss of human potential and social wellbeing – is significant, and to a fair extent is preventable.

Any society that was truly caring and compassionate – and sensible – would realise that investing in creating the healthiest possible start for every single child in Canada would have huge health, social and economic benefits. So why don’t we do so – why is this not a national and provincial priority? Why is there not a Ministry of Healthy Child Development, instead of a hodge-podge of poorly funded programs across multiple ministries?

If we want to have fewer Tyler’s, we need to get very serious about this. Governments that fail to invest in a comprehensive healthy child development strategy are guilty of wasting a huge amount of human and economic potential. They are also guilty of neglect every bit as much as parents who neglect their children.

Tyler’s story – Early support is vital

Tyler’s story – Early support is vital

Last week I told Tyler’s story, a fictionalized account of life to the age of 30 of “a prototypical adolescent offender in Canada”, highlighting “the most common risk factors that affect Canadian youth who become involved in crime”. But the whole point of the Public Safety Canada (PSC) report from which Tyler’s story comes is that the significant loss to society that Tyler represents – not just economic loss, but loss of human potential and social wellbeing – is to a fair extent preventable.

Brain development in infancy is astonishing. According to the Centre on the Developing Child at Harvard, 1 million connections are made in the brain every second – yes, every second – in the first three years of life. The Centre notes “As early experiences shape the architecture of the developing brain, they also lay the foundations of sound mental health”.

The late Clyde Hertzman, founding director of the Human Early Learning Project (HELP) at UBC, called the way in which social and emotional experiences shape the brain ‘biological embedding’, noting in a report he led for the World Health Organization in 2007 that it influences health and development over the long term.

So not surprisingly, then, supporting healthy brain development early in life is crucial for both mental and physical wellbeing throughout life. Lets look at some early interventions which were not included in the PSC report, but that might have had an even greater impact on Tyler’s story.

In a recent presentation at the Atlantic Summer Institute in PEI Dr. Chaya Kulkarni, discussed the work of the Infant Mental Health Promotion (IMHP) initiative at The Hospital for Sick Children in Toronto, of which she is the Director. Not only are the first three years of life are key, she noted, but the mother’s emotional state and level of stress during pregnancy can affect the emotional, behavioural and cognitive outcomes of the child she is carrying.

She emphasized that relationships are foundational to achieving the tasks of childhood and that secure attachment between the infant and the caregiver (usually the parent) is key, while isolation, indifference and neglect are traumatic. Dr. Kulkarni also stressed that infants can and do experience trauma, that it is possible to detect atypical developmental trajectories in the first 6 months of life, and that children do not outgrow their early mental health problems.

In recent years, there has been a growing recognition of the traumatic mental and physical health impacts of adverse childhood experiences (ACEs). These are things like physical and emotional abuse, neglect, caregiver mental illness, household violence and poverty, effects we can see at work in Tyler’s story. Such experiences are very stressful to infants and young children, and the more ACEs they experience, the greater the impact. Such prolonged stress is toxic, and “can have a cumulative toll on an individual’s physical and mental health—for a lifetime”, the Harvard Centre notes.

So obviously we need to reduce the number of ACEs, and the evidence shows that there are several key things we need to do in the early years. The focus must be on the entire family, and on reducing the level of stress within the family. This includes reducing poverty, which is why the failure to eliminate child poverty, as the House of Commons pledged to do by 2000, is such a disgrace, a massive failure of our supposedly compassionate society that acts against our long-term interests.

Beyond that, we need to identify parents and infants that need support in becoming caring and attentive parents and developing strong attachment and positive relationships, and where necessary we need to be able to intervene to protect vulnerable children. This requires a significant investment in parent and infant health, because Dr. Kulkarni reports that there is no good system for protecting and improving infant mental health in Canada.

As the Harvard Centre notes: “By improving children’s environments of relationships and experiences early in life, society can address many costly problems, including incarceration, homelessness, and the failure to complete high school.” What a difference that might have made to Tyler’s story.

Next week I will return to the PSC report and the three child and youth interventions discussed in that report.

Tyler’s story – The price of failure

Tyler’s story – The price of failure

The 2018 annual conference of the Public Health Association of BC had a focus on violence prevention. One of the keynote speakers was Dr. Irvin Waller, a criminologist at the University of Ottawa and Canada’s leading expert on violence prevention. He shared the key findings of a 2016 research report from Public Safety Canada called Tyler’s Story. It is the fictionalised story of life to the age of 30 of “a prototypical adolescent offender in Canada”, highlighting “the most common risk factors that affect Canadian youth who become involved in crime”.

The report notes that “the majority of Canadians engage in some form of delinquent behaviour during adolescence”, but “most people eventually outgrow these behaviours”. However, more than 94,000 young people aged 12-17 years old – approximately 4% of the Canadian youth population – were accused of a Criminal Code violation in 2014. Of course, not all of them go on to a life of crime, but for those who do, it is a damaging and expensive experience, not only for Tyler, but for all the other people whose lives he touched and who were harmed by his actions.

It is an important story for those of us interested in improving the health of the population, because the story also estimated both the economic costs to society and, more important still, the potential inteventions that might have changed his life course for the better, and the potential savings.

Tyler did not get a great start in life. He was born to a young high school drop out and his father had a history of property crimes. Before the age of two, Tyler had come to the attention of the child welfare agency as his mother struggled to raise him largely on her own. Perhaps not surprisingly, he had behavioural problems which meant he could not attend daycare, but had to stay with a neighbour or at home with his father – now out of jail.

However, his father was abusive, and before the age of 5, Tyler was in foster care, and over the next 5 years had three foster homes, and thus three changes of school. He became aggressive and disruptive, was diagnosed with ADHD and given medication, and moved to a fourth foster home. A victim of teasing at school, he became violent and ultimately was suspended for fighting.

In high school, where he continued to be disruptive and was often suspended, Tyler hung out with a bad crowd and before long they were stealing to buy cigarettes, alcohol and marijuana. He was caught, of course, and in Grade 10 received his first youth sentence – probation. While still 16 he dropped out of school, and before too long, his aggressive behaviour ended in an assault charge and landed him a six-month sentence in a secure youth custody facility.

There he partnered up with a drug dealer, eventually was caught dealing cocaine and, now 18, was sentenced to an adult jail term. The pattern of assaults and drug dealing and jail continued, and by age 30, Tyler had spent 10 years of his life in custody.

And the cost of all this? The report’s authors estimate the costs to society at $1.4 million, largely from the child protection and justice system, but also costs for medical care for victims and for property damage. This does not include the stress and mental pain and suffering endured by his victims, nor does it include the health and social harm arising from his drug dealing. And this is just for one person’s action, never mind the hundreds, perhaps thousands more who are the larger population of which Tyler is a representative.

But as noted, the report also points to three proven evidence-based interventions that, had they been available and implemented, might have diverted Tyler to a different path, preventing much of this harm. The first of these, if implemented at age 6 – 10, might have saved society almost $1.2 million, not to mention the avoided mental and social harm, while the latest, at age 15 – 17, could still have saved almost $900,000.

More about this next week, along with ideas for even earlier interventions that might help change Tyler’s story.

Distorting climate science is bad for our health

Distorting climate science is bad for our health

Dr. Trevor Hancock

20 August 2019

701 words

Last week I critiqued the errors and distortions in an article by Gwyn Morgan presenting what he claimed to be a set of ‘little-known facts’ and myths about climate change (“Climate change myths and utter hypocrisy”, 4 August 2019). This week, I turn to some of the other examples of misrepresentations, half-truths and obfuscation in that article.

First, Morgan completely misrepresents the Intergovernmental Panel on Climate Change (IPCC) in writing that they “would have us believe that fossil-fuel emissions are the sole reason for climate change”. They do nothing of the sort. In fact, in the IPCC’s 2014 Synthesis Report Summary for Policymakers, Figure SPM.2 shows that in 2010 CO2 was accountable for 76 percent of total annual anthropogenic (human-created) greenhouse gas (GHG) emissions; the remaining 24 percent is due to other greenhouse gases – methane (which does come in part from the fossil fuel industry), nitrous oxide (also comes in part from fossil fuel combustion) and fluorinated gases.

The chart also shows that CO2 from fossil fuel combustion and industrial processes accounted for 65 percent of all GHG emissions in 2010 – up from 55 percent in 1970, while CO2 from forestry and other land use accounted for 11 percent – down from 17 percent in 1970. So while the contribution of fossil fuels has grown since 1970, the IPCC is clear that it is far from the sole reason.

Morgan also asks: “But what about urbanization and deforestation”? As noted above, the 2014 IPCC report also shows that forestry and other land use contributes to GHG emissions. Indeed, just after Morgan’s column was published, the IPCC released a special report on climate change and land, which is hardly ignoring the issue.

Morgan then minimises the data on rising sea levels. Again citing NOAA data, which states that sea levels “continue to rise at the rate of about one-eighth of an inch (3.2 mm) per year”, he writes, correctly, that “At that rate, a house built 10 feet above sea level today would still be nine feet, seven inches above sea level in 40 years“. But this serves to downplay the serious and legitimate concerns about sea-level rise. In fact the same NOAA website notes “Sea level rise at specific locations may be more or less than the global average due to local factors”.

Indeed, a recent Government of Canada report projects 75 – 100 cm (2.5 – 3.25 feet) increases in sea level along Canada’s Atlantic coast by 2100, with northern BC and the lower mainland seeing 50 – 75 cm (1.6 – 2.5 feet) increases. In referring to the report, Professor John Clague, an earth sciences professor at Simon Fraser University, notes “[A few millimetres per year] may not seem like a lot to many people . . . But if it’s accompanied by strong storms, you really have an exacerbated effect”.

Morgan also seeks to minimise Canada’s contribution to greenhouse gas emissions, writing that we contribute a “miniscule 1.6 percent” of global CO2 emissions; what difference can we make, he implies. Well, apart from ignoring the fact that we are only 0.5 percent of the global population – so we are emitting more than three times our ‘fair share’ – this is simply an argument for doing nothing. If this attitude were adopted by all governments it would result in no action; exactly what much of the fossil fuel industry wants.

Morgan also derides the declaration of a climate emergency, claiming it is not a national but a global emergency. But a recent Environment and Climate Change Canada report – which Morgan fails to note – reports that Canada is warming twice as fast as the world average, and Canada’s North is warming even more rapidly, which certainly makes it a national issue.

In fact, the reason it has become an emergency is largely due to the deliberate misrepresentation of the science, and attacks on the scientific community by the fossil fuel industry and its political supporters over recent decades. This has resulted in ‘business as usual’, eroding the window of opportunity for action, so what was not an emergency has become one, threatening the health of millions of people. This is a cost the fossil fuel industry seems willing to impose on us.

Facts matter in discussing fossil fuels

Facts matter in discussing fossil fuels

In an article first published in the Financial Post and re-published here two weeks ago, Gwyn Morgan – “a director of five global corporations, including the founding CEO of Encana Corp.” – put forth a “list of little-known facts” about climate change. His article elicited a flurry of supportive and dismissive letters. What none of them really did was to take a hard look at these supposed ‘facts’, which often turn out to be mathematically unsound, scientifically illiterate, distorted or misleading. If this is representative of the quality of thinking and the level of mathematical and scientific literacy among the directors of global corporations, no wonder we are in such trouble.

But while tempting to ignore his article, it cannot go unanswered. It is in its way a classic example of the misleading propaganda that the fossil fuel industry puts forth in its attempt to minimise the significance of climate change at the expense of the long-term wellbeing of humanity and the natural systems upon which we depend.

Citing a 2018 report from the U.S. National Oceans and Atmospheric Administration (NOAA), one of Morgan’s first ‘facts’ is that “The concentration of CO2 in the atmosphere is now one molecule per 2,500 molecules, compared with one molecule per 3,000 molecules 50 years ago. That’s an average growth rate of just 10 molecules per year.”

I have no idea from where he gets “10 molecules per year”. I suspect he is subtracting 2,500 from 3,000 and then dividing 500 by 50 years, which is mathematically incorrect. Bear with me, there is some math involved, but it’s important to understand attempts like this to pull the wool over our eyes.

If the baseline is 3,000 molecules, and 50 years ago I had one molecule, then today, with one molecule per 2,500 molecules, I would have 1.2 molecules of CO2 per 3,000 molecules, an increase of 0.2 molecules per 3,000 molecules over 50 years, or 0.004 molecules per 3,000 molecules per year, far below the 50 molecules he suggests – which might make it seem even less important.

But he fails to point out that the increase from 1 to 1.2 molecules per 3,000 is a 20 percent increase in the proportion of CO2 over the past 50 years. In fact, it is more than that. The NOAA report he refers to notes that the CO2 level in December 1969 was 324 parts per million and in December 2018, almost 50 years later, it was 409 ppm. This is an increase of 85 ppm of CO2 over the past 50 years (much less than Morgan’s 500), which is a 26 percent increase.

To put this in context – which Morgan does not – at a global average of 405 ppm in 2017, “carbon dioxide levels today are higher than at any point in at least the past 800,000 years”, according to the NOAA’s Climate.gov website. Moreover, “the annual rate of increase in atmospheric carbon dioxide over the past 60 years is about 100 times faster than previous natural increases, such as those that occurred at the end of the last ice age 11,000-17,000 years ago”. That is why we have global over-heating and rapid climate change, with all the harm that results, including harm to human health.

Furthermore, “10 molecules per year” is a nonsensical statement without reference to a volume or a denominator. Ten molecules per year globally? In a millilitre? Per million molecules? I can only assume that “just 10 molecules per year” is an attempt to downplay the importance of parts per million of CO2 and to make the scientific concerns seem silly in every day terms – after all, who cares about “just 10 molecules per year”?

Now all this may seem a bit abstract, but it is vitally important, because public discussion needs to be informed, not mis-informed, if we are to make good decisions. If the media are going to continue to publish this sort of article they should come with a warning: “Caution – this article may be mathematically and scientifically illiterate and a misrepresentation and distortion of the facts and thus may be hazardous to your health and that of your descendants”.

Next week, I will discuss other problems with Morgan’s article.

One Planet Saanich – Thinking globally, acting locally

One Planet Saanich – Thinking globally, acting locally

Dr. Trevor Hancock

7 August 2019

700 words

I noted last week that Saanich is one of five municipalities around the world participating in a One Planet Cities initiative organised by Bioregional, a UK-based NGO. The idea is simple: How do we reduce our overall ecological footprint (about half of which is carbon emissions) to just take our fair share of the Earth’s resources, instead of the 3 – 5 planet’s worth we currently use?

Based on Bioregional’s ten ‘One Planet’ principles, the initiative addresses the ‘usual suspects’ of sustainability – energy, transportation, food, materials and waste, water, green space and so on. But Bioregional begins with three principles about people and community: Health and happiness, equity and the local economy, and culture and community. This helps us focus on why we are doing this; to enable us all to lead good quality lives, within the ecological constraints of our one small planet.

During the first year, which just ended, twelve Saanich-based organizations have created One Planet Action Plans or Scans. In addition to the municipality iteself, these include several schools, a college, businesses, NGOs and a church (see www.oneplanetsaanich.org for details). So what exactly are they doing, or planning to do?

First, Saanich itself has conducted a Sustainability Scan of the municipality. Based on Saanich’s Ecological Footprint, the report identifies several priorities related to reducing food waste and adopting a more plant-based diet, reducing the energy consumed in our buildings and infrastructure, reducing dependence on fossil fuel-based transportation and reducing the overall consumption of ‘stuff’ (consumable goods).

Importantly, the Scan notes the many potential areas of synergy between the ten areas of action defined by the Principles. For example, it looks at how a focus on local and sustainable food production with reduced meat and dairy consumption and reduced food waste can improve health and wellbeing, reduce environmental impact from animal wastes and intensive agriculture, strengthen the local economy, reduce water consumption and waste production and reduce the energy use and greenhouse gas production that contributes to global heating.

We can see how these ideas carry forward in the action plans of the twelve pioneering local organisations. The four schools (Artemis Place, Reynolds Secondary, Claremont Secondary and Mount Douglas Secondary), as well as Camosun College, all have initiatives that address food production, consumption or waste and provide hands-on learning in school gardens, land conservation or farming. In addition, there are projects in rainwater collection, a clothing swap and surveys and advocacy in support of public transportation.

Among the private sector participants, Beespot is working to build compact Green Passive House neighbourhoods, while the purpose of Bumblebee Electric Vehicles, which is a Community Contribution Company, is to accelerate widespread adoption of electric vehicles and solar energy products. In addition, both the Uptown retail centre and the Mt. Tolmie branch of the VanCity Credit Union are taking a number of actions.

The two NGOs are Haliburton Farms and Creatively United for the Planet. Haliburton is a community organic farm that has been advancing sustainable food in the region since 2001; it is linking its education work to the One Planet Principles and is accessing clean transportation options for deliveries with Bumblebee. Creatively United is focused on the arts and communication, and is creating videos to showcase local leaders who are providing positive and sustainable solutions. Finally, the Unitarian Church has initiated a Carbon Challenge to motivate members to change their driving and flying habits, install electric vehicle chargers, share recipes to encourage low-carbon food choices, and undertake advocacy to senior levels of government about climate action.

A celebration of the first year of work was held in June at the Horticultural Centre of the Pacific, and both the Mayor of Saanich, Fred Haynes, and the CRD Chair, Saanich Councillor Colin Plant, were there to acknowledge these pioneers. This is important, because we need political commitment to move this approach forward, increasing the number of participating organisations and expanding it to the whole of the CRD and beyond.

But while we can show leadership locally, we cannot do this alone. An important part of our local footprint comes from the activities of the provincial and federal governments and large corporations elsewhere. They too must become One Planet organisations, for all our sakes.

One Planet Communities – More than a climate change strategy

One Planet Communities – More than a climate change strategy (Published as ‘One planet’ communities look forward)

Last week I noted that on July 29th we reached Earth Overshoot Day – the day when humanity’s overall Ecological Footprint (EF) exceeded the Earth’s ability to replenish sufficient biocapacity to meet our demands.  However Canada, with an EF per person equivalent to 4.75 planet’s worth, passed its overshoot day on March 18th.  This week, I want to focus the issue more locally.

I live in Saanich, the largest municipality in the region. It also happens to be one of two local municipalities – Victoria is the other – that has had its EF estimated by Jennie Moore and Cora Hallsworth. The method they used – based on household expenditure data – gives an EF of 3.3 gigahectares (gha) per person, but this does not include two key components not considered part of household expenditure: Federal and provincial government services and the value of acquisitions of new or existing fixed assets (property, plant and equipment) by the business sector and governments.

Together they add a further 0.87 and 1.08 gha per person, so the total for Saanich is about 5 gha per person. This is roughly three times the Earth’s annual biocapacity, which is 1.7 gha per person, meaning Saanich’s Earth Overshoot Day is on day 122 of the year – May 2nd. So ever since then, we have been consuming more than our fair share of the Earth’s biocapacity.

Happily, Saanich’s EF is considerably less than the 4.75 Earths for Canada as a whole. This may be because most of our electricity is from hydro and we have a milder climate than much of Canada, so our energy use for heating and cooling is less. Additionally, we do not have heavy industry here, nor do we extract fossil fuels. In fact, we are more in line with European cities; a study of the Mediterranean region by the Global Footprint Network found the EF of 4 Italian and 2 Spanish cities ranged between 3.34 and 4.89 gha per person, or about 2- 3 Earths, while a separate study of three Portuguese cities found the EF falling within a narrower range of 3.76 – 4.08 gha, or about 2.5 Earth’s per person.

Nonetheless, with an EF of three Earths, we need to reduce our footprint by about 70 percent, but how do we do this while at the same time maintaining a good quality of life and good health for all who live here? There are important clues in the data on Saanich’s EF; roughly half is due to food, one quarter to transportation, one sixth due to buildings and the remaining one-tenth to ‘consumables’.

If we look at food, almost three-quarters is due to our consumption of animal products, while a similar proportion of transportation is due to private vehicle use and about the same proportion of the building EF is due to the energy used for heating and electricity; for consumables (clothes, electronics and other household goods), almost all of the EF is due to the energy and materials used in their production.

Put simply, we need to shift our diet to be more plant–based; move our transportation to more walking, biking and public transit (and working from home or close to home) and the use of clean energy vehicles; make our buildings more energy efficient and their energy sources clean and renewable, and buy less stuff, instead re-using and repairing. In many cases, these changes will also be good for health.

Importantly, while carbon emissions from fossil fuel use are a large part of the EF, there are many other aspects of our EF that need to be addressed, such as pollution, resource depletion and the loss of biodiversity. So all municipalities need to move from a focus primarily on climate action to a more comprehensive One Planet strategy.

Fortunately, not only has the EF of Saanich been measured, it is also the only local municipality that has an initiative underway to address the need to become a ‘One Planet’ community. It is the only Canadian municipality in an international project run by Bioregional, a non-profit consultancy in the UK that has been championing the ‘One Planet’ approach for almost 20 years. Next week, I will discuss the early work of One Planet Saanich.

Ooops, we have overshot the Earth’s capacity

Ooops, we have overshot the Earth’s capacity

Tomorrow, July 29, is Earth Overshoot Day, according to the Global Footprint Network; the day each year on which “humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year”. In other words, it is the day on which our overall Ecological Footprint (EF) exceeds the carrying capacity of the Earth.

The Network measures the EF by converting our demand for food, fiber products, timber, land for urban infrastructure, and forest to absorb our carbon emissions from fossil fuels, into a single unit: the land and sea area in hectares needed to meet that demand. Actually, it is an underestimate, because it does not include some impacts that cannot be measured that way: air pollution or toxic chemical wastes, for example, or species extinctions.

This ‘footprint’ is then compared to the biocapacity of the Earth, which is the amount of land and sea (forest lands, grazing lands, cropland, fishing grounds, and built-up land) needed both to replenish the resources we use and to absorb the wastes we produce. The most important of those wastes is carbon dioxide, the main driver of global overheating; it has more than doubled since 1970 and now makes up 60 percent of the entire global EF. At the same time, this should serve to remind us that climate change is not the only challenge we face; 40 percent of the EF is not carbon dioxide, but our use – and over-use – of forests, foodlands, fish, minerals and other materials.

We have been exceeding the Earth’s biocapacity for 50 years, beginning in 1969 – ironically, the year we set foot on the moon. At the global level in 2016 (the latest data available), we used the equivalent of more than 1.7 planet’s worth of biocapacity overall, which is clearly unsustainable – we only have one Earth. The Network estimates that if present trends continue, we will need the equivalent of two Earths by 2030.

The date of Earth Overshoot Day has gotten steadily earlier in the year, as population has grown and the economy has boomed. The good news is that the rate at which Earth Overshoot Day moves up on the calendar “has slowed to less than one day a year on average in the past five years, compared to an average of three days a year since overshoot began in the early 1970s”. However, it is still moving in the wrong direction.

But high-income countries such as Canada use far more than their fair share of the Earth’s biocapacity, which means they have a much earlier Earth Overshoot Day. Canada’s EF in 2016 was the equivalent of 4.75 Earths, putting our Overshoot Day on day 77 of the year – March 18th. Ever since then, we have been using more than our fair share of the Earth, while others get much less – in fact, not enough in many cases to meet their basic needs for adequate levels of human and social development.

So what should we take from this? Perhaps the most important point is that while the climate emergency is real and must be addressed urgently, at the same time we have to act on all the other aspects of our EF. We need not just a climate strategy but a One Planet strategy; how do we reduce our EF to the equivalent of one planet’s worth of biocapacity – our fair share – which would be an almost 80 percent reduction for Canada as a whole. And how do we do so while maintaining a decent quality of life and good health for everyone who lives here?

The Earth Overshoot website has some useful ideas, focusing on five key areas for action: How we design and manage cities, how we power ourselves, how we produce, distribute and consume food, how we help nature thrive, and how many of us there are.

Overall, they estimate that in order to use less than 1 Earth before 2050 we need to move Earth Overshoot Day back by five days every year. This is of course a huge challenge – but so was getting to the moon. Its amazing what we can do when we put our minds to it.
