The grand canyon is not devoid of life.
Now we're getting to the issue that I brought up earlier - aesthetic ethics, and the idea of leaing wilderness 'as is'. After all, without a wilderness, are we really Americans? The frontier-thesis and all that...
"Well yes, that's because they have much shorter life spans then humans. It still takes millions of generations (I really have no idea how many) for diseases to adapt, and that is the point I was making. Eco-systems evolve at the same sort of rate."
It takes many generations for adaptations to be acclimated in an entire species, but even within the space of a human lifetime, demographic changes in the populace can be seen. Notice, for example, how short people were 300 to 400 years ago. We consider Napoleon short, but in his time he wasn't all that much shorter than his peers.

Well, once we develop the technology to make terraforming Mars practicable (like being able to get there in a few days) humans will use it. And probably screw the place up bigtime in the process.
That's no bad thing because the next planet we try to terraform will probably be in somone else's solar system so it would be better to make the mistakes in our own back yard first and learn from them.

Aren't you guys up to your eyeballs in moose, cause you
killed off ALL the wolves? And then finland was planning
on getting rid of the moose as a traffic hazard and
"damaging to the forest"
The day we can terraform a planet is the day we'll
understand how one works. Don't hold yer breath
on that one.

Sure, go ahead. But pray tell me this: How in god's name are you going to "create" carbon dioxide? There may be oxides in the soil, but I think that there is a deficit of carbon on Mars. This means that you're going to have to import carbon to Mars. Do we have that much to spare?
Has anyone given much thought as to whether mars is really able to hold a sufficient atmosphere? It is after all smaller than earth and has less gravity. How much carbon dioxide will it take to raise the atmospheric temperature to a habitable level? There is such a thing as too much carbon dioxide. If the level is too high your system can't efficiently excrete carbon dioxide from the lungs, which screws up your blood pH and reduces oxygen intake.

How about a artifical meteor shower from the asteriod
belt?

What would that accomplish? Are asteroids chock-a-block rich in carbon dioxide, or are we just venting our frustration that the only other planet in our solar system that we ever had a hope of settling turns out to be unfixable?

Chock full of ice and rocks, and they'll warm things up
on impact. Their is enough out there to build a small planet. We could make Mars bigger.
I not an expert but i believe they are also carbon rich.

Heat limestone, you get CO2
