摘要

Marine mammals have been exploited by humans for centuries. Many species have been driven to very low population levels by past hunting. But most of these have recovered. This was largely due to the fact that, as the species became rarer and rarer, it became less worthwhile to pursue them, and generally a more abundant species was turned to. This concept of a species being too rare to make it worth exploiting is known as “economic extinction.” Luckily for the animals, and for those of us who care about them, economic extinction generally comes before biological extinction, and so therefore may give the species a second chance. It is probably the main reason we have only lost four species of marine mammals in centuries of killing them and chasing them to all corners of the Earth.
