There’s an absolutely brilliant lecture online by my grad school classmate Jon Foley about global food security. (You can skip the first 14 minutes of introductory material.)
Jon thinks there is hope. But he also thinks there are problems. And what’s most important, he does the numbers, and doesn’t always reach the conclusions you expect. For example, he explains that a latte is 300 times worse than a plastic bottle of water, in terms of water security.
Starting with humanity and then proceeding through reason. This is the type of thinking we need. Please watch it.
