Yep... And they actually are a natural impediment for wind, cyclones, hurricanes, tornadoes .. stuff like that. And why does that matter? ... Well because we are not supposed to have too much wind, because there will be too much evaporation and too much moisture will be trapped in the atmosphere/clouds ... and it stops raining as often as before.. and that meaning when it rains, it causes floods where it breaks, and not being able to contain them. Also the forests provide extra shade and fodder that prevent evaporation and keeps regions moist/humid more or for a longer period of time in the direction that the wind blows.

And then comes a "but" from the sheeple ... and they say "so what if it is trapped in the clouds/atmosphere!" ... Well... the atmosphere/clouds are full of sulfuric acids and other things that come from volcanoes and will make stuff acid... besides the amount of pollution that come from US / China / Europe ... that sh!t is just amazing how red clouds spin on the same latitude and longitude around the globe and keep adding massive critical pollution mass. It actually hurts to breath sometimes, like your throat just feels dry and starts burning/itching/irritating... And I live in a damn forest for hundreds of miles and I still get sometimes twice per month a weird smog... And in those days I just wish it will rain 24/7.

Also... that guy should know that 500 years ago.. Nevada was not a desert! It was a green place... And everything is a big f'ing cycle in the ecosystem... you have trees.. you have water... you have squirrels.. they sh!t... micro-organisms eat their sh!t... those organisms create natural fertilizers and also prevent mold from happening... stuff grows faster and bigger.. then deer/buffalo eat the sh!t that grows fast... more sh!t.. more moist.. more growth... wolves/jackals/lynx/bear/foxes eat the overpopulated sheep/goats ... birds scavengers eat the reaming stuff.. then more birds... more sh!t... with seeds in their sh!t... that sh!t drops from the sky in other places... and trees appear in other places... And everything becomes homogeneous!! Like it is supposed to be... It took more than a few million years to reach to these stages and we managed to make 50% of our planet in to pure desert in the last 5-6 millennia of the "modern human" ... Why did the British and the Spaniards hard to win and not the hippie Indians??    




*Edit: There where trees in f'ing Antarctica no more than 2000 years ago... F'ing Antarctica!!
