Canada is among the world's wealthiest nations, but our wealth is not equitably distributed. Many communities, particularly northern and Aboriginal, suffer from poor access to healthy and affordable food, clean water, proper housing and other necessary infrastructure. An ironic example of this disparity is at Shoal Lake, about two hours east of Winnipeg. There, two First Nations, Shoal Lake 39 and 40, are next to the City of Winnipeg's main drinking-water supply, but Shoal Lake 40 has been on a boil-water advisory for decades.Continue reading »
Our ancestors may not have called themselves "citizen scientists" or organized to collect data for scientific inquiry, but they were keen observers of the natural world. Their survival often depended on being able to tease apart nature's complexity — where to find game and when to sow seeds, collect berries and prepare for winter or bad weather.
But our modern, technology-obsessed lives increasingly divorce us from nature, with consequences for our health and well-being. Numerous studies now remind us of what we know intuitively: Spending time in nature makes us feel better — helping with depression, attention deficit disorder, recall and memory, problem-solving and creativity. People who spend more time outside are also physically healthier.Continue reading »
It's become a cliché to say that out of crisis comes opportunity. But there's no denying that when faced with crises, we have choices. The opportunity depends on what we decide to do.
What choices will we make when confronted with the fact that 2014 will likely be the hottest year on record? According to the U.S. National Oceanic and Atmospheric Administration, global land and sea temperatures up to September's end tie this year with 1998 as the warmest since record keeping began in 1880. "If 2014 maintains this temperature departure from average for the remainder of the year, it will be the warmest year on record," a NOAA statement says.
The idea of a right to a healthy environment is getting traction at Canada's highest political levels. Federal Opposition MP Linda Duncan recently introduced "An Act to Establish a Canadian Environmental Bill of Rights" in Parliament. If it's passed, our federal government will have a legal duty to protect Canadians' right to live in a healthy environment.Continue reading »
Have you heard of flupyradifurone? Probably not, unless you work for the federal government agency poised to approve this new pesticide for use in Canada. But take note: This new "F" word is bad news for bees.
Flupyradifurone is an insect-killing systemic pesticide similar to the controversial neonicotinoid, or neonic, family of bee-killing chemicals. When applied to seeds or soil, it's absorbed by plant roots and travels to leaves, flowers, pollen and nectar, making the plant potentially toxic to insects.
