Chicken farmers on the Delaware?Maryland?Virginia peninsula are introducing between 20 and 50 tons of arsenic to the environment annually, and researchers aren?t sure where it?s ending up. At some point, this arsenic could contaminate surface and groundwater.

The poultry industry in the region raises 600 million chickens annually, according to the Department of Agriculture. In the process, these chickens are fed organic arsenic compounds, like roxarsone, to control infections and increase weight gain. Keeping within U.S. Food and Drug Administration limits, little of the roxarsone is retained in the meat. Most of it ends up in the 1.5 million tons of manure produced annually by the chickens.

The trash that ends up in the ocean has become a vehicle for the transportation of exotic marine life into new ports. This is threatening global biodiversity, particularly in the Southern Ocean.

David Barnes of the British Antarctic Survey (BAS) made a 10-year study of human litter, mostly plastic, that washed ashore on 30 remotes islands, from the Arctic to the Antarctic. His team found that litter has almost doubled the spread of alien species in the subtropics and more than tripled it at high latitudes.

Jackie Alan Giuliano writes in the Lycos website that two key figures have resigned from the U.S. Environmental Protection Agency (EPA) in the last month. Both officials, the chief investigator for the EPA’s Ombudsman Office and the Ombudsman himself, stated in their resignation letters that the EPA has covered up the existence of deadly pollution in the area of the destroyed World Trade Center towers in New York.

At a New York public hearing in February, Hugh Kaufman, then chief investigator for the EPA’s Ombudsman Office, told a group of scientists, residents, and small business owners that he believed the EPA was deliberately not testing the air quality in the World Trade Center area properly and covering up the reasons why.

Glaciologist Lonnie Thompson, of Ohio State University, wants to read the record of ancient weather trapped inside ice from Alaskan glaciers that date back thousands of years. He?s going on his 44th expedition to the remote region of the Wrangell-St. Elias Mountain range on the U.S.-Canadian Border. There, in an ice-filled area between two mountain peaks, he and a team of researchers will use a solar-powered drill to pierce the ice cap and retrieve these records.
