What weighs less than a paperclip, tastes terrible and can travel thousands of kilometres without a map? Hint: this delicate critter is tawny-orange with black veins and white spots and has been mysteriously absent from Canada this summer. Continue reading David Suzuki: Help solve an orange-and-black mystery
Scientists are more certain now than in 2007 that humans are largely responsible for global warming, and that it’s getting worse and poses a serious threat to humanity. Continue reading David Suzuki: IPCC report shows action on climate change is critical
Resolving the problem of climate change will cost, but it will be much more expensive to follow the defeatist advice of industry shills, whose greed and lack of care for humanity will condemn our children and grandchildren to an uncertain future. Continue reading Attacks on climate change science hinder solutions
From Arctic tundra to primeval rainforest to arid desert, our natural world is being fragmented by ever-expanding towns and cities, roads, transmission lines and pipelines, and pockmarked by mines, pump jacks, flare stacks and other infrastructure used to drill, frack and strip-mine fossil fuels. Continue reading Tahltan’s Sacred Headwaters defence has deep roots
Many urban areas have built or are considering building waste-incineration facilities to generate energy. At first glance, it seems like a win-win. You get rid of "garbage" and acquire a new energy source with fuel that’s almost free. But it’s a problematic solution, and a complicated issue. Continue reading Incinerating trash is a waste of resources
The science is clear: human-caused climate change is the most pressing threat to humanity, and we must work to resolve it. We don’t have time for debunked conspiracy theories. Continue reading Conspiracies fuel climate change denial and belief in chemtrails
Rather than rationalizing our continued use of fossil fuels in the false belief that technology will enable us to carry on with our destructive ways, we really need governments, scientists and industry to start taking climate change and greenhouse gas emissions seriously. Continue reading Is geoengineering a silver bullet for climate change?
We need to get a handle on the toxic chemicals we use to grow food. If our practices kill insects and birds that make it possible to grow crops, we’re defeating their purpose and putting ourselves and the rest of nature at risk. Continue reading Scientists work to solve mystery of dying bees
As people begin to pick up their lives, and talk turns to what Calgary and other communities can do to rebuild, safeguarding our irreplaceable, most precious flood-protection assets should be given top priority. Continue reading Working with nature can protect us from floods
Most cities in Canada and the U.S. are lacking in infrastructure to move millions of people safely and affordably. With some notable exceptions, such as Vancouver and Calgary, no successful rapid transit infrastructure projects have been built in Canadian cities for decades. Continue reading Great public transit makes for a great city
Scientists often come up with new discoveries, technologies or theories. But sometimes they rediscover what our ancestors already knew. A couple of recent findings show we have a lot to learn from our forebears – and nature – about bugs. Continue reading Bean leaves, bedbugs and biomimicry
Does regular time in nature make you calmer? More alert? Happier? Let’s all get into the nature habit. It can make our lives better. Continue reading Stressed at work? Add a daily dose of green
