Water wont ever be a problem. We can maake all the fresh water we want, from salt water... all it takes is lots of energy. In fact there has been much talk of fighting the illegal Mexican immigration problems by 'giving' Mexico the technology to build nuclear reactors for no other purpose than to change salt water into fresh, allowing them to turn their barren land into a fertile area (and thus keep them from wanting to come here). I didn't say it was a good plan, but it has been discussed. The point is, we can make fresh water.
We could also alleviate our dependence on middle eastern oil 100% (and thus remove ourselves from their politics, their wars and their plight), if we simply wanted to. You can thank the tree-huggers for our dependence on foreign oil. OMG we can't drill in Anwar, a few caribou might die. No, its much better to purchase our oil from foreign countries, thereby weakening the US dollar by sending vast amounts of money overseas (and to the middle east no less), and putting American citizens, people like you and me, in harm's way defending our foreign dependence. Yes that's right, in order to save off the possibility of *some* caribou dying when/if we drilled in Anwar, we'd rather send our sons and daughters to the middle east to die fighting over their oil. Clearly caribou come before people.
Or drilling off the coast of Florida... we cant put up any new oil rigs out there, fear of oil spills ruining the environment and all that. Smart to be prudent right? But oops, along comes Cuba and leases the rights to drill in their waters to China. So now we have a situation where we cannot drill offshore of Florida for fear of the environmental impact, but Chinese oil rigs will be popping up along our coast, within sight of shore, to drill OUR oil, only to refine it and sell it back to US. And, do you really think China will be concerned about the environmental impact in OUR waters? more so than we ourselves would have been? Nope, us American's with all our technology, all our environmental laws and safety nets in place, cannot drill for oil in our coastal waters anymore.... but the notoriously 'messy' and careless Chinese will be. I hope those of you who fight against drilling in Anwar, or off our coastlines, or who fight new nuclear power stations... I hope you are all happy with the results of your short-sightedness.
Long live freakishly absurd environmentalism I say.
