Championing and accelerating solutions to the climate crisis

The way we raise animals is destructive to humans, animals and the environment, says cardiologist and entrepreneur Uma Valeti. He presents a solution that doesn't require you to give up your favorite protein-packed meals: cultivated meat, grown directly from animal cells. Reportedly some of the "most chicken-y chicken" you'll taste, Valeti envisions how such cultivated meat could save billions of animal lives, improve human health and help protect our planet.

Global food production — from meat to grains — accounts for a third of all greenhouse gas emissions, says sustainability scientist Jonathan Foley. He presents a portfolio of data-backed solutions to build a better food system world-wide, starting with four key steps to cut emissions.
