The January 3 issue of The Economist Magazine offers a special report on the challenges confronting the world’s oceans. The nine-part package of stories covers a range of topics, including global warming, dying coral reefs, bottom trawling, dumping of sewage and trash, oxygen-choking algae blooms resulting from too many nutrients (often from fertilizer runoff), overfishing, and more. It’s a fine compilation of a broad range of ocean issues, well worth a read.
