Over 20,000 people were involved in removing algae off the coast of Qingdao, China. This city of course is host to the Olympic sailing regatta and the algae must be removed. China’s news agency reported that over one third of the waters designated for the Olmypic competition was covered. Untreated sewage has been dumped into the sea, rivers and tributaries by Chinese coastal cities. What’s in the waste? Nitrates. The same nitrates that play havoc with your home reef aquarium. Apprently this hasn’t been in the first time in which this algae has been a problem, as red tides of algae bloom along sections of China’s coastline in months past. Granted the Chinese government denies any such pollution from facotries or raw sewage from being put into the coast. That sounds like any proud governement, however we are just glad this won’t interfere with the sailing races.
