Climate Change

When humans hunt and fish, they tend to favor animals that provide significant resources. In the oceans, whales, sharks and other large vertebrates have been targeted for centuries, and while the international ban on whaling has helped some species recover in select areas, many populations have fallen to a fraction of their natural levels.

One of the most persistent arguments against efforts to stop man-made global warming is that environmental regulations — mandates to reduce carbon emissions or require polluters to pay, for example — put people out of work. Proponents of such laws argue that they can create jobs by encouraging technological innovations. Critics say they burden business.
