Passage Summary: We've passed many green laws, but things are still going downhill. Therefore, passing more laws won't help.

Conclusion: Additional environmental regulations are not the correct solution for environmental issues.

Reasoning: Extensive regulations have been passed since the 1970s, yet the environment is still getting worse according to environmentalists.

Analysis: The flaw here is a failure to consider the 'counterfactual'—what would have happened without the regulations. Just because the environment is worsening doesn't mean the regulations are failing; they might be preventing a total catastrophe. The argument treats the lack of a total cure as proof that the medicine is useless. Look for an answer that points out the argument ignores the possibility that regulations have actually slowed the rate of deterioration.
