What is one economic effect of environmental-protection laws

There are more economic benefits than environmental protection.

Explanation:

First and foremost, environmental protection protects human health. Clean air, clean water and a healthy environment generally improve people's quality of life. Otherwise, if people become ill because of the polluted environment, then the government must allocate millions of resources to cure those people. The same is true of the environment if an area is poisoned, it needs to be cleaned, and that involves enormous amounts of money. In both cases, the government will save vast amounts of money because it will not have to invest money to remedy any problems.
