Those crystals are nothing compared to what may be seen at the following:

A question at the end asks: "Should we continue to pump water to keep the cave available so future generations may admire the crystals?" geologist Juan Manuel García-Ruiz said. "Or should we stop pumping and return the scenario to the natural origin, allowing the crystals to regrow?" Plant life in the Mohavee (Mojave?) Dessert is worth far more consideration. Greens are all that recycle coal, and anything we can do about dessert expansion is good, although it would not hurt to hav numbers like the ratio between coal used to pump water and carbon captured. I suspect that worse ratios are in Canadian farming when you add tractors and chemicals. Plus, especially down there near the equator, a lot of it ends up as atmospheric moisture, and for the last two or three years, Alberta's been in drought. _______ http://ecn.ab.ca/~brewhaha/ The above opinions are mine; all mine.
