>Why aren't we first trying to terraform wastelands here to see how actually feasible the idea is?

We already tried and FAILED.

The major flaw in the $150 million Biosphere 2 project has been discovered by a leading geochemist and his student, raising questions of whether the venture in the Arizona desert will be corrected in the interest of serious science or will be doomed to repeated cycles of failure in the years ahead. In theory, the experiment is to last 100 years.
As an attempt to create a balanced and self-sustaining replica of Earth’s ecosystems, Biosphere II was a miserable (and expensive) failure. Numerous problems plagued the crew almost from the very beginning. Of these, a mysterious loss of oxygen and widespread extinction were the most notable.Not quite 18 months into the experiment, when oxygen levels dropped to the point where the crew could barely function, the outside managers decided to pump oxygen into the system so they could complete the full 2 years as planned.The designers of Biosphere II included a carefully chosen variety of plant, animal, and insect species. They anticipated that some species would not survive, but the eventual extinction rate was much higher than expected. Of the 25 small vertebrates with which the project began, only 6 did not die out by the mission's end. Almost all of the insect species went extinct, including those which had been included for the purpose of pollinating plants. This caused its own problems, since the plants could no longer propagate themselves.

Its going to happen in less than 10 years.
>There are
>4 space stations - alright I believe in it
> 2 Moonbases - What Moonbases ?
>and 1 Mars colony in the works - What Mars colony ?

>Its going to happen in less than 10 years.

HAHAHAHAHAHAHAHA!

Do you really think that sending few people on space stations VERY CLOSE TO EARTH IN SPACE TERM is the same thing as building and estabilishing regular space colonies MUCH FURTHER FROM EARTH ?

> I expect at least half to be here in the 2020s.

Then you will be dissapointed that this wont happened in the 2020s or 2030s.
