It depends on how you see environment safety.

Either you want to safe dieing species and biomes, or you want to safe somehow the global ecosystem that keeps us alive.

First is illusionary, second is apparently too expensive according to the industrial nations.

If you can place solar in the desert without killing food supply, then do it!

The USA will have a big problem producing food once the Mediterranean climate zone wander north.

Also a lot of USAs food production is supported by a big underwater reservoir that is very close to dry up....

However I never see that they adress this issue....
