Interesting. The real problem is population - worldwide. Too many people. Not enough water, not enough food, not enough common sense. We just keep breeding more and more. Wars help but not really a lot.

The only real solution is probably space but who really knows. I live in a town that doesn't just border the Olympic national park but has some of the park in its city limits. That also means that we have a LOT of trees edging into the city limits as well. I have often wondered what is going to happen when it catches fire. That hasn't happened in the long time and, when it did, it didn't spread far as there is little wind in our direction as we are at the base of the Olympic Mountains as well which protects us. Still, its a worry but we also sit on top of the Cascadia Subduction Zone as well and when that goes off ...........
