By Alister Doyle, Reuters. For GSS losing Biodiversity chapter 7. Excerpt: The amount of fish in the oceans has halved since 1970, in a plunge to the "brink of collapse" caused by over-fishing and other threats, the WWF conservation group said on Wednesday. Populations of some commercial fish stocks, such as a group including tuna, mackerel and bonito, had fallen by almost 75 percent, according to a study by the WWF and the Zoological Society of London (ZSL). ...The analysis said it tracked 5,829 populations of 1,234 species, such as seals, turtles and dolphins and sharks. It said the ZSL data sets were almost twice as large as past studies. ...The study said the world's fishing fleets were too big and supported by subsidies totaling $14-35 billion a year. Later this month, governments are due to adopt new U.N. sustainable development goals, including ending over-fishing and destructive fishing practices by 2020 and restoring stocks "in the shortest time feasible"....  http://www.reuters.com/article/2015/09/16/us-environment-oceans-idUSKCN0RG1JW20150916
