Marine pollution : what everyone needs to know / Judith S. Weis.
Marine pollution occurs today in varied forms--chemical, industrial, and agricultural-and the sources of pollution are endless. In recent history, we''ve seen oil spills, untreated sewage, eutrophication, invasive species, heavy metals, acidification, radioactive substances, marine litter, and overfishing, among other significant problems. Though marine pollution has long been a topic of concern, it has very recently exploded in environmental, economic, and political debate circles; scientists and non-scientists alike continue to be shocked and dismayed at the sheer diversity of water pollutan
