How can we reduce Air, Water , other Pollution?

It's called Pigouvian taxes in textbook. But regulation might also be fined. Carbon trade and cap are used in many countries right now.

Or subsidy for alternative energy sources, like Solar and Wind.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
