A Conservation group wants to stop a solar plant?

I haven't posted for a while but when I inadvertently came across this article, Conservation group sues to stop California solar plant, I was really taken back.  I thought " how on earth could a group called the Western Watersheds Project be against solar energy?  Just how does a solar panel disturb a water shed?  If and when it rains, and if that rain doesn't hit the ground because it hits a solar panel, what will happen?  Will the precious water be transported to the Eastern Water Shed?  My bet is it will run off the solar panel and wind up on the ground.  Now this is just an intuitive guess, but please correct me if I am wrong.  So I looked up this organization and mission statement. "The mission of Western Watersheds Project is to protect and restore western watersheds and wildlife through education, public policy initiatives and litigation. Ahhhh!  Thats it  they seem to be partly profesional litigators. 

"The complaint said the project's approval process failed to analyze and mitigate the Ivanpah plant's impact on migratory birds, the desert tortoise, which is a threatened species under federal law, desert bighorn sheep, groundwater resources and rare plants.

Oakland, California-based Brightsource has taken measures to assuage environmentalists' concerns about the project. In October, the privately held company reached a deal with litigious environmental group The Center for Biological Diversity to acquire thousands of acres of habitat for the desert tortoise and other rare species."

So I ask, At what point is man allowed to change his environment?  At what point does it stop?  Yes any thing that is changed does effect something else.  Build a road and nature will react.  Deer will eat the grass in the right of way.  Tortoises will slowly try to cross the road, some successfully,  others not so much.  Does that mean don't build roads?  Do we build wildlife bridges and tourus tunnels every 100 yards?  Should we force feed Pandas and artificially inseminate them because the are on an evolutionary dead end of specialization?

It's time to really think about nature.  Man is neither strong, or fast.  Man has inferior teeth for tearing meat or chewing vegetation.  Claws?  Nope.  Man is a creature that survives and thrives because he changes his environment rather than adapt to it.  His primary tool; his brain.  Man survives by interpreting his environment rationally and using his intellect to survive.  Cold?.....  Make clothing......  Hungry?.....  Farm.  Hot?....... Aiconditioning.  Want to get laid?  Lipstick, tramp stamp and fake tits.  (Did I make my point?)

Now I'm not saying it's OK to srtipmine the earth and not resore it.  Thats like saying, "I'm going to eat all my food now.  Screw saving any for the winter.  Thats not rational as is the actions of overspecialized litigation hounds bringing suit.
