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. Hosted on Acast. See acast.com/privacy for more information.

What if you could eat chicken nuggets without harming a chicken? It's possible through "cellular agriculture," says Isha Datar.

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.
