you should consider writing a novel, i bet you would be good at it. Fiction of courseHere is how this works in reality. America stops using oil, gas and plastic. We all give up what we love and essentially give up first world living. We wreck the economy. Impoverish our people and China/ India and possibly Russia take our place, burns all that oil anyway without any environmental regulation the human carbon footprint INCREASES and climate change accelerates even faster making all of our sacrifice meaningless. On top of that it makes us the bad guys for doing that to our own people much like Stalin's 10 year plan.
Furthermore and I've said this before but when people begin to starve they will kill off wildlife to feed their families. When they start to freeze they will cut down the forests to heat their homes. A thriving US economy in all sectors is vital to having a healthy environment.
