A recent U.S. Geological Survey estimates that the Pacific walrus population nearly halved between 1981 and 1999, the last year for which demographic data are available. The study notes that the decline was most severe in the mid-1980s, and then moderated in the 1990s. Currently, the USGS is working to obtain more recent population data of the Pacific walrus. This information will be vital because the U.S. Fish & Wildlife Service is expected to determine whether the Pacific walrus should be listed as threatened under the Endangered Species Act in 2017.

Incineration or burning of any fuel leaves a series of residual gases that promote global warming; however Altos Hornos de Mexico (AHMSA) agreed with the UN a methane gas burning system in its coal mines that greatly lessens the impact on the environment.
AHMSA informs that to operate a coal deposit, methane gas is extracted in advance by drilling, to keep the safety of workers. If this gas is discharged into the atmosphere, will produce a warming effect...

Many homeowners strive to have the picture-perfect green lawn. But how can that be achieved in an environment where water in parts of the country is becoming scarce and the use of pesticides and fertilizer is being discouraged?
Researchers from two Big Ten universities hope that they will be able to find an answer. Scientists from Rutgers University and the University of Minnesota, both members of the Committee on Institutional Cooperation – an academic consortium of Big Ten universities – will be working together over the next five years to develop an environmentally friendly grass that is more resistant to disease and drought and a better economical choice for homeowners.

With supermarket milk cheaper than spring water, it's time to rethink the modern dairy industry. It's not just the milk that's become a throwaway product - the high-octane Holstein cows that produce it are also in the knackers yard after just two or three lactations, the living waste of a loss-making, environment-trashing industry.

Deepwater Wind has received the final federal approval needed to build the Block Island Wind Farm — a project that remains on-track to be the nation’s first offshore wind farm.
The project’s lead federal permitting agency, the Army Corps of Engineers, granted its approval Sept. 5. With the Corps’ permit, the Block Island Wind Farm has now been completely reviewed, and approved, by nine state and federal agencies: Army Corps of Engineers, Federal Aviation Administration, U.S. Fish & Wildlife Service, National Oceanic and Atmospheric Administration, Environmental Protection Agency, Coast Guard, Rhode Island Coastal Resources Management Council, Rhode Island Department of Environmental Management and the Rhode Island State Historic Preservation Office.

Sandy Oliviera has raised monarch butterflies in her East Providence backyard for 25 years. In 1998, she helped 125 monarch caterpillars transform into butterflies, and then released them to the wind.
"I began to feel like a butterfly factory that year," Oliviera said. Each time her husband or daughter collected milkweed to feed their captive caterpillars, they returned with more eggs or caterpillars to raise. Some days, Oliviera released a dozen newly emerged butterflies, to the pleasure of her 8-year-old grandson who let them rest on his head before they flew away.
This summer, for the first time, Oliviera hasn't found a single monarch egg or caterpillar, and hasn't seen any monarch butterflies.
