The climate has always been changing...you can look at the other planets in our solar system as proof of that.
Now, if we're just talking about environment, yes, programs are out there to promote awareness. It starts with the youth! I remember being in grade school and being taught about not polluting, and to this day I don't throw things out the car windows because of that. So, if groups would keep introducing actions to the youth, the environment will remain clean.
