We can use process of elimination on this problem; we need to identify why B and E are incorrect. To start off, B is incorrect because saying that environmental protection in North America will not affect Europe or Asia does not contribute to the overlying question; why is environmental protection important in North America? E is incorrect because saying what the environmental protection policies need does not contribute to why it is important for North America. Another thing to consider about answer B is that environmental protection in North America actually will affect Europe and Asia because members of both countries interact with Americans in some way at some time. Trading can be compromised if North America does not have exceptional environmental protection because food can be contaminated, materials can be at the lowest of quality and not be able to last long enough for mass reproduction, and even the citizens interacting can be affected with environmental sicknesses and diseases!
