We should of course care about the state of the olam haze that Hashem created for us. There are a lot of non-controversial things that we do: do not things away, fruit trees, city layout, not damaging property.
The problem start with philosophies that make hard-to-prove claims that require, somehow, for money to flow from us to them. So, it then becomes entirely possible to pursue these goals at the expense of simple things we are required to do. Say, decrease population or at least have less kids to save the planet; close down nuclear and coal powerplants to increase dependency on Arabs and Russians.
Bottom line, we are for environment – goodm healthy Jewish environment.
