No decision happens in a vacuum, Allan.  Eliminating environmental regulations around the fossil fuel industry isn't just about greenhouse gas emissions.  It's about safety standards in offshore drilling, limiting chemical pollutants in fossil fuel exploration and extraction, controlling waste and byproduct emissions and protecting public drinking water and sensitive ecosystems.

A reasonable person might presume that these standards would remain in place, but that's not what Trump has promised.  He has promised to eliminate ALL regulations around fossil fuel exploration and severely curtail (if not eliminate entirely) the EPA as an organization.

You seem to want to paint this sunny picture in which Trump will reach the perfect balance of industrial development against environmental protection... but no such balance exists.  In some cases you simply have to choose your money or your health... and based on our history as a society, money tends to win.
