As many countries move away from big hydro projects, B.C.’s government must decide whether to continue work on the Site C dam. The controversial megaproject would flood a 100-kilometre stretch of the Peace River Valley and provide enough power for the equivalent of about 500,000 homes. The B.C. Utilities Commission, an independent body

Government Inaction, Industry Tactics increase Caribou Risks
October 5 came and went, and Canada’s boreal woodland caribou are still in trouble. That was the deadline the federal government gave provinces and territories five years ago to come up with caribou range plans for the iconic animals. Not one met the deadline. Why should we care about caribou?

What does climate change have to do with economic growth? Canada’s prime minister and premiers signed a deal in December to “grow our economy, reduce greenhouse-gas [GHG] emissions, and build resilience to the impacts of a changing climate”. The Pan-Canadian Framework on Clean Growth and Climate Change outlines plans for

Photo by NOAA Satellites When the Aztecs founded Tenochtitlán in 1325, they built it on a large island on Lake Texcoco. Its eventual 200,000-plus inhabitants relied on canals, levees, dikes, floating gardens, aqueducts and bridges for defence, transportation, flood control, drinking water and food. After the Spaniards conquered the city

Spring flooding in Canada this year upended lives, inundated city streets and swamped houses, prompting calls for sandbags, seawalls and dikes to save communities. Ontario and Quebec’s April rainfall was double the 30-year average. Thousands of homes in 130 Quebec municipalities stretching from the Ontario border to the Gaspé Peninsula flooded

Grizzly bears venturing from dens in search of food this spring will face landscapes dominated by mines, roads, pipelines, clearcuts and ever-expanding towns and cities. As in years past, they’ll also face the possibility of painful death at the hands of trophy hunters. British Columbia’s spring bear hunt just opened. Hunters are fanning across the province’s mountains, grasslands,

The federal government recently created two marine protected areas in the Pacific region and has committed to increase ocean protection from one per cent to 10 by 2020. But will this be enough? Canada has the longest coastline of any nation, but our country doesn’t end at its ocean shores. With

Neskantaga First Nation in Ontario has had to boil water since 1995. “We’re over 20 years already where our people haven’t been able to get the water they need to drink from their taps or to bathe themselves without getting any rashes,” Neskantaga Chief Wayne Moonias told CBC News in 2015. Their

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

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

The U.S. election was a chilling illustration of the atrocious state of public discourse. It doesn’t bode well for a country once admired for leadership in education and science. As public relations expert and former David Suzuki Foundation board chair James Hoggan writes in I’m Right and You’re an Idiot, “polluted public discourse

In July, a pipeline leak near Maidstone, Saskatchewan, spilled about 250,000 litres of diluted oil sands bitumen into the North Saskatchewan River, killing wildlife and comprising drinking water for nearby communities, including Prince Albert. It was one of 11 spills in the province over the previous year. In October, a tugboat

I’ve often thought politicians inhabit a parallel universe. Maybe it’s just widespread cognitive dissonance, coupled with a lack of imagination, that compels them to engage in so much contradictory behaviour. Trying to appease so many varying interests isn’t easy. Rather than focusing on short-term economic and corporate priorities, though, politicians should

Salmon have been swimming in Pacific Northwest waters for at least seven million years, as indicated by fossils of large saber-tooth salmon found in the area. During that time, they’ve been a key species in intricate, interconnected coastal ecosystems, bringing nitrogen and other nutrients from the ocean and up streams and rivers to spawning grounds, feeding whales, bears and eagles and fertilizing the magnificent coastal rainforests along the way.
David Suzuki: Cultural and Ecosystem Diversity Key to Resilience

It’s been shocking to watch news of the Brexit vote in Britain, Donald Trump’s promise to build a wall between Mexico and the U.S. and the ongoing threats and violence against ethnic minorities in many parts of the world. I’m not a political or social scientist, but my training as a biologist gives me some insight.
When I began my career as a scientist, geneticists were starting to analyze the molecular properties of single genes within a species. When we started looking at highly evolved species such as fruit flies, we thought we would find that their genes had been honed through selection over time, so they would be relatively homogeneous within single species. Examining one kind of protein controlled by a specific gene, we expected to find them all pretty much the same. Instead, we learned there was a great deal of heterogeneity, or diversity. A gene specifying a protein could exist in a number of different states.
This is now called “genetic polymorphism” and is considered to be the very measure of a species’ health. Inbreeding or reduction of a species to a small number reduces genetic polymorphism and exposes harmful genes, thereby rendering the species more susceptible to sudden change. In other words, genetic polymorphism confers resilience by providing greater possibilities as conditions shift.
