If we cannot find a way to replace non-renewable resources with renewable forms, we're toast. We have to stop developing farmland into suburbs or highrise apartments. If we don't limit population, nature will do it for us.
Good point. And I think we see that all the time, with major earthquakes, floods, famine, etc., that Mother Nature wipes out everything in the path of destruction with one fell swoop. Too bad that it has to hurt so bad, though. Just like God, Mother Nature doesn't consider pain as a factor in regulating life.
As we crowd more and more people, into smaller spaces, we get more violence and more filth, just check out most large, crowded intercity areas.
We've weakened our immune systems by medicating every sniffle and overprotecting our children from childhood diseases, leaving us dependent on drug companies when the next worldwide pandemic comes along.
