Without the EPA many of our largest cities would look like Beijing with citizens required to wear gas masks.  Without the EPA our rivers would be stagnant mires of toxins and dead fish.  Without the EPA every neighborhood could have a chemical dump next to the playground.  Without the EPA I shudder to think of the environmental disaster that we will be leaving for our children and their children.  Never in US history has any polluter voluntarily cleaned up their act.  Being environmentally responsible costs big polluters money and they would far rather have that money than give a darn about leaving a livable environment for the rest of us.  Just another disaster that Trump will leave behind in his total devotion to his big money pals.
