Major shifts in fisheries distribution due to climate change will affect food security in tropical regions most adversely, according to a study [pdf] led by the Sea Around Us Project at The University of British Columbia. In the first major study to examine the effects of climate change on ocean fisheries, a team of researchers […]
From TreeHugger: From the Arctic to the Rockies to the Mediterranean, species large and small are changing their migratory patterns and seeking more hospitable homes. Why? Climate change affects weather conditions, hunting grounds, and the availability of water and favored food supplies. Those that can up and move are the lucky ones–for now–but each […]

A furious row has erupted in Canada with conservationists desperately […]
Posted by Nate Hagens at The Oil Drum …The liquid tailings, a by product of the oil sands mining process, contain naphthenic acids, unrecovered hydrocarbons and trace metals, making it toxic to aquatic organisms21 and mammals22. Operators are required to store tailings waste on site in large containment dykes because the water is too toxic […]
By Lewis Smith Attempts to save the bluefin tuna from extinction suffered a serious setback yesterday when the European Union dropped its demand for commercial fishing of the species to be banned. A rearguard action by Mediterranean fishing nations, including Spain, Italy and France, blocked moves to get the European Union to support a worldwide […]
Groundwater-quality data from a sampling of 1,329 wells in 19 states were analyzed. Chloride concentrations were greater than the secondary maximum contaminant level established by the U.S. Environmental Protection Agency of 250 milligrams per liter in 2.5 percent of samples from 797 shallow monitoring wells and in 1.7 percent of samples from 532 drinking-water supply […]
By MARIAN WILKINSON ENVIRONMENT EDITOR ENVIRONMENT groups are calling for a permanent ban on ”deadly” artificial fishing devices used to attract huge tuna catches in the Pacific after scientific reports found that stocks of bigeye tuna are collapsing. Greenpeace activists aboard the Esperanza confiscated several of the devices known as FADs (fish aggregation devices) in […]
