Way too much! I work in the Enviornmental field performing many cleanup activities in old abandoned factories, mines and outdoors! First of all let me say that I am a conversation its but not an Enviornmental whacko! The EPA has become too powerful and needs to have its wings clipped substantially! Let the state's totally manage this as the already have their own Departments of Natural Recourses that actually do the enforcing! But EPA needs to be taken down. As for Climate Change? This whole universe is 99% carbon to include the human body and some clowns want us to erase What? We will not go back to horse and buggy days! Petroleum and Coal are here to stay until someone invents Dilithium Chrystals!!!!! And your windmills and solar panels are not the answer!
