As was stated earlier, as the industrial revolution began to take hold people started suing factories for polluting their air and their properties.
This created a small but growing industry of pollution detectives which would track the source of the pollution on one's property so that they could build up a good enough case to take on the factory.
Then these factories started getting tired of being sued for polluting so they turned to the government. The government stepped in and said "we will protect you from pollution with our regulations". They created an Environmental Protection Agency which would set standards on how much pollution a factory could create and fine them if they were not in compliance with those standards. They could still pollute but only within the legal guidelines, and if they went beyond those guidelines, the government got some money. Needless to say, this created a single location for the corporations' lobbyists to go to and gain favor and thus they were basically legally allowed to pollute from then on.
So thanks to the EPA, it is very difficult to sue a company for polluting and an industry of pollution detectives was squashed early before it could become economically feasible for most people.
