In this brief clip novelist John Green points out yet another way in which the world is better and offers some thoughts (prompted by Bill Gates) on the importance of free time and (preferably less polluting) sources of energy. It's worth 3 minutes and 50 seconds of your time. (The Hank he addresses is brother.)
The Bill and Melinda Gates annual letter he's talking about can be read at this link.
Hundreds more clips from John and Hank Green are on their massive number of YouTube channels, and my other references to them (and in passing other things that are green) are here.
