RA3 - I know how you feel and I happen to agree with you, but Cow here wants to take us down the road a see where it goes. Come to think of it my neighbors cow is always doing that. Anyway, I don't really see your point CowMan for the reason you state:

Case in point:

Mt. St Helens explodes.
Toutle River is "nuked", a veritable fish wasteland.
River left alone, you know, returned to nature.
Forward a few years later. Habit improves.
Voila, "wild" steelhead return.
Daily News - Steelhead miraculously return to Toutle.
WDFW - Toutle open to fishing, but be nice to nates.

Thing is, without mans meddling with the fish or its habitat these "wild" fish are amazingly resilient. And I think that what RA3 is pointing out is if we would just respect the fish and its habitat there would be no need to clone for future generations. The fish do very well on their own given the opportunity (good habitat) and would only benefit further from our protection.

But running with your "end of world" scenario, maybe we should have kept some of Elvis's DNA in case something happens to us. Never mind we've still got Michael J.

Cow, can't believe I've wayed in on this one 3 times already. But then you dropped the "pie" and I had to run with it.
