Tai is coming back for season 2...and he needs your help!

Can our generation make Earth Day cool again? (Bonus from What On Earth): 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.

How do we fix recycling?: Tai tries to do his part by recycling whenever he can. But it turns out just tossing stuff into the blue bin doesn't do a whole lot: less than 10 percent of our plastic waste actually gets recycled, with the rest either ending up in landfill, burned or shipped overseas! How did we get here? Tai turns to people looking for creative ways to tackle trash around the world, and learns how we can all be more mindful of what we decide to throw away. In this episode Tai talks to: - Calvin Lakhan, research scientist at York University - Olivia Kwok, supervisor of Waste and Diversion Programs with the city of St. Albert - Nate Maynard, Taiwan-based sustainability consultant and environmental researcher - Andrea McKenzie, zero waste project engineer for the city of Vancouver by Tai Asks Why

How do animals know where they’re going?: We know birds can travel large distances day or night, rain or shine, even if they’ve never migrated before.

Can we keep eating meat without destroying the planet?: To Tai, nothing beats cutting into a perfectly cooked steak or wolfing down a big, juicy cheeseburger. But lately he’s been paying more attention to the buzz around going meatless in the fight against climate change. “Plant-based” foods like beefless burgers and chickenless nuggets have made their way into grocery aisles and fast food chains. But are those actually better for the environment? What exactly is our appetite for meat doing to the planet? Tai investigates. In this episode Tai talks to: - Brent Kim, researcher at the Johns Hopkins Center for a Livable Future - Jody Puglisi, professor of structural biology at Stanford University by Tai Asks Why
