The worst culprit is standing radio towers with wires and tall, lit buildings. It's estimated a billion birds are killed every migration. It's less likey a bird will exhaust itself flying over woods where it can land anywhere, any time. It must be very tiring to fly over a stinky, hot, fouled city where you don't know what the hell is down there.
I, firmly, believe that cities are the biggest ecological disasters we've ever created.
I really believe, too, that future cities will be nothing more than centers for culture, the arts and entertainment without the need for the masses of information workers that clog the roads, burn large percentages of our annual oil usage, and produce millions of tons of carbon dioxide and other pollutants.
