Zoos are becoming facsimiles - or perhaps caricatures - of how animals once were in their natural habitat. If the right policies toward nature were pursued, we would need no zoos at all.
Before I had kids I'd go out on the road for months and months at a time, but now I don't think I'd want to do that anymore, because I'd miss too much time at home, so it's just a matter of monitoring how much work that I do and how much time I'm on the road.
