A pollinator paradise in the middle of the street

To mark the show’s anniversary, we ask what Canada has learned about tackling climate change since our debut in 2020, starting with lessons from the Covid-19 pandemic. And, we discuss what climate action could look like over the next five years.

From the Best of What On Earth — Glaciers are rapidly retreating in Canada’s Rockies and that’s making it more hazardous to navigate some alpine routes. In this documentary, we visit Banff National Park to meet guides who are adapting to the different ways climate change is altering a once familiar landscape. Plus, what you need to know about how older people can stay safe in extreme heat.

If Canada wants to be net zero by 2050, more than a million small businesses will have to make the green transition. And while some intrepid business owners are already trying their best to navigate a more eco-friendly path, others say it’s a big ask, especially when many are already struggling to balance the needs of price-wary shoppers with a thin bottom line. We’ll dive into their journey, and learn more about the supports that could change the game.

A year and a half ago, Adrienne Crowder caught an episode we did about a free university course on climate change. She took it, she loved it, and she wanted more. So, she started a network amongst her classmates: ordinary Canadians who support each other to make change in their lives. We hear from many of them, as we kick off special coverage to mark five years of What On Earth.

Ottawa's moves to fast-track resource projects with Bill C-5 are resurfacing concerns about Indigenous consultation. But what does it actually look like when Indigenous people push back against resource projects and take control of climate stewardship on their land? To find out, we head to the heart of Tsleil-Waututh traditional territory near Vancouver. The work they’ve done to restore local ecosystems is not only good for the climate, it's also a way to assert their rights. Then, we'll hear from an Anishinaabe expert who says this is just one example of how taking land back can be climate action.

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.

This year’s fire season is on track to be one of the worst on record. It’s displacing thousands, including many First Nation communities. We hear from those forced to flee far from home, about the fear they face. We explore the political push to make sure Indigenous communities can take the lead when fires break out. Then, we check in on an Indigenous-led emergency management company that puts this idea into action by supporting evacuees in Toronto.

Meet the ‘cunning foxes,’ student activists who saved the Gachibowli forest in southern India. What On Earth’s youth climate action columnist Aishwarya Puttur shares what she’s heard from protesters who took a stand in defence of a cooling green space in the urban centre of Hyderabad – and what lessons the protest holds for climate action everywhere.

This World Oceans Day, we're sharing a story from The Outlaw Ocean — an urgent look at the migration crisis unfolding in the Mediterranean Sea. Pulitzer Prize-winning journalist Ian Urbina shares insights into how climate change is driving a massive global migration, with 150 million people expected to move in the next 50 years. He follows the story of one rural farmer, a young father from Guinea-Bissau.Find the full series here: https://link.mgln.ai/oo-woe

From scientists to lobbyists to youth risking arrest, meet the people leading the resistance to anti-climate policy in the United States. Since Donald Trump’s second term began, hundreds of pro-climate policies have been rolled back or undermined, leaving many American climate advocates shocked and dismayed. But now, they’re pushing back. We hear about the tactics leaders are using to shift public opinion ahead of the U.S. midterms in 2026.
