We have about 8 billion people in the world. We'll level off at 10 billion. There are very good reasons to think that that it won't go above 10 billion. It's not going to keep growing. Yeah, because people aren't having as many children. They're not having as many kids. So this all averages out and you will settle out at about 10 billion. But my point is, we live in sort of safer times than ever before, even if it doesn't feel that way.
