Can Healthy Food Save the Planet?

You know the saying "you are what you eat." But the way we currently eat is in fact ruining our health, the health of others, and that of the planet. Unhealthier food is now deadlier than alcohol, drugs, and tobacco use combined. 2.1 billion people are overweight, yet we eat more sugar, fat, and red meat than ever. Still, 821 million go to bed hungry every night. On top of that, our food is the main cause behind species extinction and a third of all global greenhouse gas emissions. So, can we feed a growing population without destroying the planet and ourselves? Science has no clear answer to this question. That's why we gathered 37 of the world's best scientists to determine what it is and how to get there.
