    World Water Day reminds us not to take clean water for granted

    March 17, 2016

    Earth's oceans, lakes, rivers and streams are its circulatory system, providing life's essentials for people, animals and ecosystems. Canada has one-fifth of the world's freshwater, a quarter of its remaining... More »

    Change is in the air

    March 10, 2016

    We only recognize the significance of events in the context of history. I recently had a day like any other except it made me wonder if we're on the verge of historical change. More »

    Will cap-and-trade slow climate change?

    March 3, 2016

    The David Suzuki Foundation and others have long argued that provinces and the federal government should put a price on carbon, through carbon taxes, cap-and-trade or a combination of both. The urgent need to address global warming means provinces that have adopted cap-and-trade need to strengthen it by ensuring emissions drop faster and polluters pay a price that truly reflects the damage caused by carbon pollution.

    Public attention in Canada has largely focused on domesticated European honeybees, but research indicates the honeybee crisis is part of a wider problem affecting hundreds of lesser-known but crucially important wild bee species. More »

    Energy storage gives renewables a jump-start

    With the urgent need to cut greenhouse gas emissions, governments need to provide incentives for rapid renewable energy development and deployment. Considering how quickly computer technology and other human inventions have advanced, it's easy to see that barriers to a clean-energy shift are more political and psychological than technological.

    It's time to protect the Great Bear Rainforest's grizzlies

    February 11, 2016

    The agreement between government, industry, First Nations and environmental groups to protect much of the Great Bear Rainforest should be celebrated. However, while the agreement helps protect grizzly bear and other wildlife habitat, it doesn't protect the bears themselves, contrary to B.C. Premier Christy Clark's claims at a news conference. Hunting grizzly and black bears in the Great Bear remains legal. More »

    Solar: A brilliant way to get energy

    February 3, 2016

    Every hour, the sun bathes the Earth with enough energy to supply our needs for more than a year. There's no reason we can't harness more of it to cut back on polluting, climate-altering fossil fuels. More »

    Paris changed everything, so why are we still talking pipelines?

    January 28, 2016

    I don't get the current brouhaha over Kinder Morgan, Keystone XL, Northern Gateway or the Energy East pipelines. Why are politicians contemplating spending billions on pipelines when the Paris commitment means 75 to 80 per cent of known fossil fuel deposits must be left in the ground? More »

    Environmental rights are human rights

    January 21, 2016

    Canada has come a long way, but we can't be complacent. We must work to maintain and strengthen the rights of all Canadians, to build an even better Canada. That means giving all Canadians the right to a healthy environment. More »

    We are the world; we must act on that understanding

    January 14, 2016

    Even with a government sympathetic to environmental issues, we won't act deeply and quickly enough or prevent new problems because we haven't addressed the root of our environmental devastation. More »
