Critical Thinking Questions 1. Propose two alternate hypotheses for why gray whales have been sighted in areas of the world where they were not previously known to inhabit. 2. If climate change is negatively affecting a marine mammal that is a pro- tected species, should activities that cause climate change be made ille- gal? Obviously this would be difficult to enforce because the causes are indirect, but it is illegal to harm or hinder species protected under the Endangered Species Act. Ponder this fact and make an argument for or against legal repercussions for causing climate change.
