Meat Food Waste has Greater Negative Environmental Impact Than Vegetable Waste
Published Aug 16, 2015 - 6:29:38 PM
Approximately 31 percent of food produced in the U.S., or 133 billion pounds of food worth $162 billion, was wasted in 2011 according to the United States Department of Agriculture (USDA). Now, University of Missouri researchers have found that the type of food wasted has a significant impact on the environment. Although less meat is wasted (on average) compared to fruits and vegetables, the researchers found that significantly more energy is used in the production of meat compared to the production of vegetables. This wasted energy is usually in the form of resources that can have negative impacts on the surrounding environment, such as diesel fuel or fertilizer being released into the environment.
Government Documents Reveal That Killing Cormorants Won't Help Columbia River Salmon
Published Aug 12, 2015 - 2:03:56 PM
Conservation groups today called for an investigation after agency documents, released last week under court order, showed that killing double-crested cormorants will not benefit salmon and steelhead in the Columbia River Basin. The U.S. Fish and Wildlife Service’s own biologists found that fish not eaten by cormorants would be eaten by other predators, but nevertheless authorized the killing of more than 10,000 double-crested cormorants and destruction of more than 26,000 cormorant nests on East Sand Island near the mouth of the Columbia.

Research shows catastrophic invertebrate extinction in Hawai'i and globally
Published Aug 11, 2015 - 7:23:47 AM
Hawai'i has been called the "extinction capital of the world." But, with the exception of the islands' birds, there has until now been no accurate assessment of the true level of this catastrophic loss. Invertebrates (insects, snails, spiders, etc.) constitute the vast majority of the species that make up Hawai'i's formerly spectacularly diverse and unique biota. A team of researchers, including scientists from the Pacific Biosciences Research Center (PBRC) at the University of Hawai'i at Mānoa, the Bishop Museum in Honolulu, Howard University in Washington DC, and the French National Museum of Natural History in Paris, recently published the first rigorous assessment of extinction of invertebrates in Hawai`i.

Greenhouse gases' millennia-long ocean legacy
Published Aug 4, 2015 - 3:22:50 PM
Continuing current carbon dioxide (CO2) emission trends throughout this century and beyond would leave a legacy of heat and acidity in the deep ocean. These changes would linger even if the atmospheric carbon dioxide concentration were to be restored to pre-industrial levels at some point in the future, according to a new Nature Climate Change paper from an international team including Carnegie's Ken Caldeira. This is due to the tremendous inertia of the ocean system.

Storm surge, high rainfall and rising sea levels provide a devastating 1,2,3 'compound flooding' punch to US coastal cities
Published Jul 28, 2015 - 5:04:43 PM
Scientists at the University of South Florida's College of Marine Science investigating the increasing risk of 'compound flooding' for major U.S. cities have found that flooding risk is greatest for cities along the Atlantic and Gulf coasts when strong storm surge and high rainfall amounts occur together. While rising sea levels are the main driver for increasing flood risk, storm surges caused by weather patterns that favor high precipitation exacerbates flood potential.
Cruelty to Endangered Orca Nets Lawsuit Against Miami Seaquarium
Published Jul 24, 2015 - 12:22:47 PM
This morning, a coalition including the Animal Legal Defense Fund (ALDF), PETA, Orca Network, and Orca Network director Howard Garrett hit the Miami Seaquarium with a lawsuit contending that the facility’s imprisonment of suffering orca Lolita—currently held without the company of any others of her kind in a cramped tank with no protection from the harsh sun—constitutes a violation of the Endangered Species Act (ESA). Under the protection of the ESA—which Lolita was granted following a successful petition from the coalition—her imprisonment and forced performances constitute an unlawful “take,” meaning that she is being harmed, harassed, or wounded.

The United States now produces about as much crude oil as Saudi Arabia does, and enough natural gas to export in large quantities. That's thanks to hydraulic fracturing, a mining practice that involves a rock-cracking pressurized mix of water, sand and chemicals.
New source of lead in drinking water identified: Galvanized steel pipe coatings
Published Jul 22, 2015 - 8:45:09 AM
When unsafe levels of lead are found in drinking water, the culprit has typically been lead pipes or lead-containing brass and bronze fittings, but in a new study researchers clearly show that lead present in the zinc coating of galvanized steel pipes can be a very significant long-term source of lead in water. Copper piping installed upstream of a galvanized steel pipe can worsen lead release from the steel's zinc coating, according to the study published in Environmental Engineering Science, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Environmental Engineering Science website until August 22, 2015.

Ocean acidification may cause dramatic changes to phytoplankton
Published Jul 21, 2015 - 8:03:05 AM
Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans worldwide. Since pre-industrial times, the pH of the oceans has dropped from an average of 8.2 to 8.1 today. Projections of climate change estimate that by the year 2100, this number will drop further, to around 7.8 -- significantly lower than any levels seen in open ocean marine communities today.
