Most people understand that human-caused climate change is a real and serious threat. True, some still reject the mountains of evidence amassed by scientists from around the world over many decades, and accepted by every legitimate scientific academy and institution. But as the physical evidence builds daily — from increasingly frequent and intense extreme weather events like droughts and floods to disappearing polar ice to rising sea levels — it takes an incredible amount of denial to claim we have no reason to worry.

Since I started working as a geneticist in the early 1960s, the field has changed considerably. James Watson, Francis Crick and Maurice Wilkins won the 1962 Nobel Prize in physiology or medicine for their discovery of the double helix structure of DNA. Researchers then “cracked” the genetic code, which held promise for fields like health and medicine. It was an exciting time to be working in the lab.

We recently highlighted the faulty logic of a pseudoscientific argument against addressing climate change: the proposition that because CO2 is necessary for plants, increasing emissions is good for the planet and the life it supports. Those who read, write or talk regularly about climate change and ecology are familiar with other anti-environmental arguments not coated with a scientific sheen.

In 2011, I travelled with my family down Yukon’s Hart River. It’s one of seven pure rivers in the Peel River watershed, a 68,000-square-kilometre wilderness that’s been at the centre of a legal dispute for many years and a land-use planning debate for more than a decade. For two weeks, we fished from the river’s vibrant green waters and gazed at the limestone and dolostone peaks of the Ogilvie Mountains.

Apparently, fossil fuel companies protect watersheds and rivers by removing oil. That’s according to comments on the David Suzuki Foundation Facebook page and elsewhere, including this: “The amount of contamination occuring [sic] from extraction is far less than if we just left the oil there to continue polluting the waterways.”

The battle lines are drawn — in some cases literally. On one side are those reaping massive profits from fossil fuels, determined to extract and sell as much as possible before the market dries up. On the other are those who see the amazing potential of energy conservation, renewable energy and other innovations to reduce pollution, greenhouse gas emissions, ecosystem destruction and exploitation of valuable non-renewable resources.

Seeing terms like “post-truth” and “alternative facts” gain traction in the news convinces me that politicians, media workers and readers could benefit from a refresher course in how science helps us understand the world. Reporting on science is difficult at the best of times. Trying to communicate complex ideas and distil entire studies into eye-catching headlines and brief stories can open the door to misinformation and limited understanding.

In the 1990s, the David Suzuki Foundation embarked on a program to develop community economic projects with coastal First Nations. Between 1998 and 2003, my wife and foundation co-founder, Tara Cullis, established relationships with 11 coastal communities from the tip of Vancouver Island to Haida Gwaii and Alaska, visiting each several times.

Since the 1950s, almost everything about work in the developed world has changed dramatically. Rapid technological advances continue to render many jobs obsolete. Globalization has shifted employment to parts of the world with the lowest costs and standards. Most households have gone from one income-earner to at least two. Women have fully integrated into the workforce, albeit often with less-than-equal opportunities, conditions and pay. A lot of our work is unnecessary and often destructive — depleting resources, destroying ecosystems, polluting air, water and soil, and fuelling climate change.

For decades, scientists have warned that we’re on a dangerous path. It stems from our delusion that endless growth in population, consumption and the economy is possible and is the very purpose of society. But endless growth is not feasible in a finite biosphere. Growth is not an end but a means.

If you fly over a forest and look down, you’ll see every green tree and plant reaching to the heavens to absorb the ultimate energy source: sunlight. What a contrast when you look down on a city or town with its naked roofs, asphalt roads and concrete sidewalks, all ignoring the sun’s beneficence! Research shows we might benefit by thinking more like a forest.

The longer we delay addressing environmental problems, the more difficult it will be to resolve them. Although we’ve known about climate change and its potential impacts for a long time, and we’re seeing those impacts worsen daily, our political representatives are still approving and promoting fossil fuel infrastructure as if we had all the time in the world to slow global warming.

How much stuff will you give and receive this holiday season? Add it to the growing pile — the 30-trillion-tonne pile. That’s how much technology and goods humans have produced, according to a study by an international team led by England’s University of Leicester. It adds up to more than all living matter on the planet, estimated at around four trillion tons.

When government biologists in Canada want to learn where caribou are, they put radio-tracking collars on some animals and monitor their movements. This gives them a rough idea of where herds are and where they travel, but it doesn’t tell them much about a caribou population’s history — travel routes before their habitat was degraded or historical feeding, breeding and calving spots.
