We made it this far without terraforming Venus. Ice ages would not affect us too much as a species, may reduce the numbers with any luck, asteroid impacts are pretty uncommon, nope, poor argument. > >This raises some other long-range questions we have not really addressed.

The dinosaurs were a group of species, individual species lasted much less time on the whole. Homo sapiens have been around about 2 million years, a mear fraction of time. Nope, I'm not worried. Besides, I would like to see a bit more evolution from our present state. > >Do we want to be sufficiently advanced so that we can create slow moving star ships >to get to the nearer stars so that when our sun blows we won't fry? Maybe I am wrong but I was under the impression that the sun was good for another 5000 million years yet, still not worried. > Tom Schneider > National Cancer Institute > Laboratory of Mathematical Biology > Frederick, Maryland 21702-1201 > toms@ncifcrf.gov The point of my earlier post is to say that OK it may be possible to terraform another planet, but do we really want to. Why stick to one solar system, lets get out there and have a look. Anyway, we may end up having to terraform the Earth at this rate!!! Shane Sturrock, Biol Lab. Canterbury, Kent, Great Britain.
