NRDC A NEW OCEAN ETHIC

摘要

Historically we've thought of our oceans as indestructible. When did that begin to change, and why? Things began to change in the 1980s and 1990s, when advances in marine science coincided with dramatic changes in the marine environment. For example, many commercial fish populations plummeted as a result of overfishing. There were severe declines in coral reefs in the Caribbean, with outbreaks of disease and episodes of bleaching. The number of large, persistent dead zones worldwide tripled, from fewer than 100 to more than 300. Once marine scientists began rigorously quantifying these changes, alarm bells went off.
