PLEASE HELP!! Why would the former Communist nations of Eastern Europe have worse pollution than other countries?

Corporations are often accused of despoiling the environment in their quest for profit. Free enterprise is supposedly incompatible with environmental preservation so that government regulation is required.

Such thinking is the basis for current proposals to expand environmental regulation greatly. So many new controls have been proposed and enacted that the late economic journalist Warren Brookes once forecast that the U.S. Environmental Protection Agency (EPA) could well become "the most powerful government agency on earth, involved in massive levels of economic, social, scientific, and political spending and interference.

But if the profit motive is the primary cause of pollution, one would not expect to find much pollution in socialist countries, such as the former Soviet Union, China, and in the former Communist countries of Eastern and Central Europe. That is, in theory. In reality, exactly the opposite is true: The socialist world suffers from the worst pollution on earth. Could it be that free enterprise is not so incompatible with environmental protection after all?
