so the simple model says we're doomed. what do we do? first: panic. whew. good. got that out of our system. feel better? second: blame someone else. it's grandpa's fault. he replaced himself with two kids. if grandpa had only replaced himself with one kid we'd be golden. forever. but the grandkids are here now and we don't have a time machine. so we could cut the population by 75%. ha ha. okay. so we could hold the population steady and cut our consumption by 75%. ha ha. or some combination thereof. any way you look at it, it's a tough choice. the alternative of course is to insist i'm completely wrong and do nothing. which is the same as doing both.
