An environmental study conducted in a particular city suggests that if a chemical plant emits more than 60 million tons of chemicals each year, the water supply will become contaminated beyond the point where filtration techniques can make it safe for drinking.

Explanation:

If the water becomes too contaminated because of the pollutants emitted by the chemical factory that the water can not be filtered to make it safe for drinking.

The only solution to check the pollution contamination in the water is by tradable permit.

By imposing tradable permit, the government put a control to the chemical industries to limit their production so that not pollutants goes to the water and water does not become incompatible for filtration. By this they can limit the pollution in water.

Thus the answer is tradable permit.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
