	Seaweed beds, the 'cradle of the sea,' vanishing http://apocadocs.com/s.pl?1265649421 ... Seaweed beds are called the "cradle of the sea" because they provide fish with oxygen, as well as places to hide and lay eggs. The symbol of marine biodiversity, however, is fast disappearing from Japan's coastal regions in a phenomenon called isoyake, or denudation of rocky shores. In 1991, an Environment Agency survey found 200,000 hectares of rich seaweed beds around the nation. The Marine Ecology Research Institute in Tokyo estimates about 20 percent had been lost by 2008. The underwater deforestation is attributed to overgrazing by herbivorous fish, pollution and other factors, but the exact causes have not been determined.
