The single most important thing for avoiding a climate disaster is cutting carbon pollution from the current 51 billion tons per year to zero, says philanthropist and technologist Bill Gates. Introducing the concept of the "green premium" — the higher price of zero-emission products like electric cars, artificial meat or sustainable aviation fuel — Gates identifies the breakthroughs and investments we need to reduce the cost of clean tech, decarbonize the economy and create a pathway to a clean and prosperous future for all.

We get it. You care about the climate crisis—but sometimes thinking about it is just too overwhelming. Well, we’re here to help with that. Host Dan Kwartler unpacks the problems and solutions behind big systemic issues in bite-sized episodes. You’ll find out which bag is best for the planet, imagine our world without humans, and follow the international journey of the very shirt on your back. Yes, we’re going to talk about the bleak stuff—it’s a crisis after all—but we’ll also share little ways you can make changes in your daily life, in your towns and cities, and at your workplaces to help change climate change. Ultimately we’re aiming for some HOPE through a focus on solutions, instead of just, you know, tumbling towards inevitable doom.

Everyone has the right to a clean environment — but major disparities exist when it comes to who faces the consequences of pollution. Environmental justice leader Peggy Shepard points to the disproportionate impact that hazardous environmental conditions have on Black, brown and Indigenous communities and challenges us to build a truly equitable future that turns "sacrifice zones" — where community health is sacrificed for the sake of development — into "green zones" that redress the legacy of pollution and harmful policies.

Your closet is likely full of all kinds of materials — leather, cotton, nylon and polyester, to name a few — that contribute to fashion's sustainability crisis. Biomaterials investigator Dan Widmaier explains how we could look to nature for sustainable replacements for these much-used materials and introduces a leather alternative made from mushrooms that looks great and doesn't harm the environment. "We can make fashion sustainable, and we're going to do it with science," Widmaier says.

What if you could eat chicken nuggets without harming a chicken? It's possible through "cellular agriculture," says Isha Datar. In a talk about cutting-edge science, she explains how this new means of food production makes it possible to eat meat without the negative consequences of industrial farming — and how it could fundamentally change our food systems for the better. "It's our once-in-a-lifetime opportunity to get a second chance at agriculture," she says.
