Pollution of the oceans
> Whether deliberately discharged or unintentionally introduced, plastic waste, pharma- ceuticals, toxic heavy metals, insecticides and other chemicals have found their way to every corner of the oceans. The consequences are catastrophic and often lethal, especially for marine organisms. The only good news is that international prohibitions of some pollutants are beginning to have an effect. Without radical changes in industry and commerce, however, the pollution crisis in the oceans cannot be overcome.
