Are leaky, old oil wells poisoning people and the planet?
“What’s there to worry about?” That’s what Alberta rancher Teresa Patry thought when her family agreed to oil wells on their property. But that changed when she, her family and her animals started experiencing a variety of health issues. And she says the province’s energy regulator is not doing enough to address her concerns. We hear about the potential links between health problems and oil and gas production. Then, we hear about a coalition of landowners, environmental groups and others working to push the oil industry to clean up its mess – for the health of communities and the climate.
A pollinator paradise in the middle of the street
From the Best of What On Earth – Don’t have a garden? Adopt a roundabout and plant things for the bees! We meet a TikToker who’s done just that. And then we travel from coast to coast to hear about a push to let sections of city parks grow a little wild. We head to one of these meadows to hear how they attract pollinators, and hear why creating “pollinator pockets” for busy bees and “hairy” moths can be a climate solution across the country – and a patriotic one at that.
Does a military upgrade mean a climate downgrade?
Canada faces a climate conundrum when it comes to the military. To maintain northern sovereignty, defence needs to adapt quickly to the warming Arctic. But even before the recent boost in investment, the military was already the single largest emitter of greenhouse gases in the federal government. So how can Canada defend the North and stick to its climate goals at the same time? Then, we hear about Canada’s new $3.8 billion investment plan to protect nature.
