What do you mean by this?
In the 60s, there were many environmental problems. It was found that DDT, a chemical used for insecticide, had many adverse effects on the environment. In 1969, the Cuyahoga River "caught fire." The water didn't catch fire, but rather the heaping amount of pollution covering the surface of the water. Instead of fireman, I believe you meant the einvornmental movement? It wasn't very popular because many people thought that helping the environment would be detrimental to the economic world. The movement attracted those people who were previously against toxic waste or nukes, though. I personally believe the environmental movement was for the better. Nixon established the Environmental Protection Agency, which helped to regulate cleaner air and overall a cleaner environment overall. Because of this movement, we have better regulations today that help us live better and cleaner lives. Although our pollution is bad, many other countries have it worse such as China and their smog problem. This movement helped spread the growing problem of environmental corruption and it definitely seems to have worked.
