Mitt Romney just wrote himself off in my book. He opposes Mr. Gingrich's plan for a moon base, and would "fire" any staffer who suggested such an idea. (Click here.)
Has anybody here thought more than 50 years ahead? By 2062, we will certainly not have enough oil or natural gas to power human activity. The US and China have extensive coal reserves, but that is hardly appealing as a long-term energy plan.
Even with voluntary, or even mandatory, population control, we will still have 7 billion, and almost certainly more, humans inhabiting the planet.
Hopefully some plan for nuclear fusion as a source of power works out, but what if it doesn't? (It's not going to be easy to re-create the interior of the sun on our planet, even in "micro-spaces.")
We know for sure that the best source of solar energy is in space. If we're not operating in that environment in 50 years' time, we risk catastrophic developments. I'm just saying that humans (and by then, our robotic extensions) will have to be very active in space.
