Thus the pie available to us certainly is far from limited for at least the next couple of generations to come. I disagree. For instance, we could hit peak oil any day, if we haven't already. We're seeing major water shortages around the U.S.. Peak oil means basically we are running out of the cheap stuff. There is more oil that we haven't tapped but up until now the price of crude has not justified the cost involved in extracting that oil. As for water shortages in this country, that's as much about poor management, lack of maintenance of the water network and its infrastructure,and a lack of easily implemented conservation measures than it is about a true shortage of water. And that's the point I was making in prior posts......that are lot of things that can be done to forestall running out.....measures that can make a significant difference. For an example, water conservation is a big issue out here in the West. CA has implemented a lot of conservation measures from covering reservoirs with sun reflecting materials, slowing evaporation, to installing minimum flow toilets and show heads. As a consequence, in spite of a large increase in population, water consumption is basically unchanged from the early 1990s[I don't remember the exact statistics but I think that's pretty close.] And again, CA has implemented only the least costly measures so far. Improving the pipe network to mitigate leaks will cost considerably more. Building more reservoirs to capture what rainfall the state does get also will cost considerably more. Its important to note here that Santa Barbara's only source for water is its rainfall. And SB only averages 13 inches per year as opposed to NYC's 38-39 inches. That's why I think we have a long way to go before catastrophe is just around the corner.
