The climate is changing. So are we. On What On Earth, you’ll explore a world of solutions with host Laura Lynch and our team of journalists. In 1970, 20 million people showed up to fight for the environment on the first Earth Day. More than five decades later, is it time for this much tamer global event to return to its radical roots?  OG organizer Denis Hayes recounts how – amidst other counterculture movements at the time – his team persuaded roughly one in ten Americans to take to the streets. As he approaches 80, Denis offers his singular piece of advice to the next generation of climate leaders. Then, environmental warriors Maria Blancas and Axcelle Campana share ideas on what a reinspired Earth Day could look like – including making it a public holiday.

A restaurant in Muskoka, Ontario is doing its best to respond if necessary, after the slate of poisonings with a more dangerous form of fentanyl in Belleville.

A unique medical team in the UK is able to treat hospitalized patients in their own homes. The team can make a diagnosis in the field, so they can offer treatment on the spot. The result? They're providing the same volume and complexity of care as a 20-bed ward, active 24/7. And it’s cheaper.
