As civilizations grew, more different pollutants were dumped into the seas. Still, this pollution did not really threaten the marine environment. The seas seemed 47 of coping with anything that people could throw at them. This situation changed, however, when suddenly factories began dumping enormous quan tities of materials into the seas. Especially in some
coastal areas near large cities, ocean pollution began to 48 marine life. For the first time, the oceans began to fail in their ability to 49 humanity’s waste.。
