Do we stand to gain anything from watching water consumption or planning development in a way that preserves space? And, more specifically, should we take these measures even if any possible benefits will not occur until after our lifetime?
I think the central issue here (completely evaded by most environmentalists) is one of property rights. An individual or corporation has a right to do whatever they want with their own property. If they own the land, they have every right to cut down the trees, etc., and nobody has any right to stop them, no matter who’s grandchildren stand to benefit.
But at the same time-- if someone or some organization engages in activities that can be proven to cause harm to other people’s property; for example, if a company is dumping pure toxic waste into a river that drains straight into your crawfish farm, and (you are able to prove conclusively that) your crawfish are growing wings and fangs as a result and attacking you whenever you try to harvest them, or whatever, then you have a legal claim against that person or organization. If you can prove that they’re damaging your property directly through their actions, then that’s illegal (and rightly so).
But the ecologists tend to totally ignore cases like that. They go after policies and new regulations, instead of investigating and helping to enforce the legitimate environmental laws that already exist (and by now, there are of course many, many laws which are not legitimate at all, yet they’re still not satisfied).
At this point (and long ago), there is no way their alleged utopic-fantasyland that future generations will supposedly grow into could ever be wonderful enough to justify the misery they are putting us through now.
And there’s never a time when the good of “the future,” or any other “greater good” can legitimately supersede individual rights (property rights).
As individual consumers, should we, now, conserve our water and preserve our space? I’ve never seen any legitimate evidence that water or space are scarce. If that ever becomes a problem, then we might want to conserve (if there is a drought in your area, it might be in your interest to conserve, but you shouldn’t be forced to do so, by anyone except the one who owns/pumps the water, who would probably do it simply by raising the price, or limiting the amount per-customer over a set time). As to space-- we’re not going to run out any time soon. Especially here in the drastically underpopulated US.
