What effects has the environmental movement had on the United States?
The environmental movement has had at least two important impacts on the United States. First, it has improved environmental quality in the country. We no longer worry about acid rain and air pollution is down. Most rivers and lakes are much cleaner than they were 40 years ago. Second, it has contributed to the deep splits between conservatives and liberals. It has become one more battle ground for us politically. This is because liberals take environmentalism as an important cause and conservatives resist it largely because it is seen as a liberal thing.
