No he didn't say that. He said reduce the world's population. You can do that by having fewer births. Over time, this will reduce the population. Or you can just put words in his mouth that's cool too. From one of the youtube comments (rarely will I quote a YT comment): "If you reduce infant mortality people have fewer children. Look it up. People overestimate their own risk of losing a kid, and tend to have more children in order to compensate."
