land scarred by forest fires erosion of ocean shorelines converging plate boundaries destruction of tropical rain forests
I gave my students this multiple choice question: There are a variety of events that can disrupt ecosystems. Some events result in local disturbances and others can affect a much larger area. Which event would most likely result in change on a global scale?

Only one answer is correct among these 4 choices:
- land scarred by forest fires
- erosion of ocean shorelines
- converging plate boundaries
- destruction of tropical rain forests

Could you tell me which one is correct?

destruction of tropical rain forests
