This is something that has always really annoyed me about this game, Hydro power plants don't have any of the negetive ramifications! When you build a dam all flood plains down stream should vanish and if a river system is dammed too many times it should turn Grassland to Plains and plains to desert! Also, the other bonuses for the river should slowly decrease down stream if dams and such are present as well as adding sickness if dammed too many times! Next, Coal power plants should remain virtually the same but there should be a building of some discription that allows cleaner burning and should halve the effect. Also, Global Warming in the game is rediculous and should be removed, fallout is enough. Fusion power should also be in the game.
