XRP brings up a good point re: tree planting. I live in the desert, and I know for a fact that there are more trees here than there were 20 years ago, let alone 200. Of course, the green whackos are mad at us desert dwellers for importing water! They push this idea of 'Xeriscape'-drought resistant plants, rocks instead of grass, etc. My neighborhood is very 'green-unfriendly':we all have lush lawns and trees, flowers, bushes,etc. Hey, we pay for the water, and it's up to the water managers to come up with constructive ways to monitor the supply and demand! (The farmers could learn to be a liittle more efficient in their water use.)
Bottom line---the only thing that will make these creeps happy is negative population growth!
