Re: ozone holes - NOT from rockets (instead, volcanoes)
"Until we launch nuclear engines that have NO air pollution, our cell phones, internet, television, and other worldwide communications are going to need *ROCKETS* to get them satellites into orbit, and those rockets are going to affect things... minimally."
Err, my cell phone doesn't use satellites, neither does my television, nor AFAIK my Internet. The only worldwide communications I do are international telephone calls and they don't use satellites either. Submarine cables, yes.
