Carbon Dioxide: Pollutant Or Plant Food?

Life evolved to live within limits. It's a delicate balance. Humans need oxygen, but too much can kill us. Plants need nitrogen, but excess nitrogen harms them, and pollutes rivers, lakes and oceans. Ecosystems are complex. Our health and survival depend on intricate interactions that ensure we get the right amounts of clean air, water, food from productive soils and energy from the sun.

The Time Has Come To Restore Protection Of Canadian Ecosystems

Canada's federal power shift provides us with the opportunity to view the United Nations' Sustainable Development Goals through a new lens. Our new government faces many challenges to restore the protection of Canadian ecosystems. After a decade of Conservative rule, I find myself, like many other Indigenous people in Canada, cautiously optimistic for the future social and ecological well-being of our nation and its role on the international stage. However, our new government will face significant challenges in living up to and improving upon their campaign promises.

1 of Every 3 Bites of Food Depends on Bees -- Let's Save Them

Bees may be small, but they play a big role in human health and survival. Some experts say one of every three bites of food we eat depends on them. The insects pollinate everything from apples and zucchini to blueberries and almonds. If bees and other pollinators are at risk, entire terrestrial ecosystems are at risk, and so are we.

Celebrate Canada's Oceans at Your Local Fish Counter

Improving the way we fish and grow seafood is critical to the survival of some of our planet's most threatened marine and freshwater species and environments. But a national sustainable seafood day is also a critical reminder that even through our everyday choices in what food we buy, we can have a profound impact on the future of life on our planet. And nowhere is that more true than at our fish counters.

Billions Of Dollars In Unrecognized Services Found Under Metro Vancouver Water

A new report values the annual services provided by aquatic areas to Lower Mainland residents. These are services that we've always treated as free because they have no current market value and are add-ons to nature-based economic activities like fisheries and forestry. The results are remarkable: our wetlands, beaches, coastal areas, lakes and rivers give us benefits to the tune of $30 billion to $60 billion every year, and that's a conservative estimate. That's like building more than 14 Canada Lines.

Learning the Value of Respect on Haida Gwaii

One of the first lessons I learned from First Nations communities was about the importance of respect. Without respect for each other, we don't listen and we fail to learn. But respect should extend beyond our fellow humans, to all the green things that capture the sun's energy and power the rest of life on Earth.

How to Become an Environmentalist

Reports about floods and droughts and sea ice and climate change get sandwiched between clips about scandals and celebrities, and so we view them as isolated events. An environmental perspective would consider the possibility that many of the events are connected to an underlying cause.
