 Concerning water pollution, Lomborg notes again that it is connected with economic progress.He also notes that water pollution in major Western rivers decreased rapidly after the use of sewage systems became widespread.Concerning waste, Lomborg notes once again that fears are overblown, as the entire waste produced by the United States in the 21st century could fit into a square 100 feet thick and 28 km along each side, or 0.009% of the total surface of the United States.
