Severe Drought Has U.S. West Fearing Worst (The New York Times): 17 rural communities in California that provide water to 40,000 people could possibly run out of water soon. Officials are saying this drought is on track to be the worst in 500 years and it has already produced dry fields, starving livestock and dense areas of smog. Farmers are being forced to give up on planting and have had to sell animals because there is not enough water. Recreational activities like fishing and camping have been banned and water use is extremely limited among residents living there.

Study: Physical, electric barriers best defenses against Asian Carp (Detroit Free Press): A recent study has found that the most effective defense against Asian Carp reaching the Great Lakes is placing dam-like structures or less expensive electric barrier systems in Chicago waterways. Other methods that were considered are strobe lights, noise makers and depleting oxygen levels in the water, but these were deemed less effective. The study found that physical separation could prevent 95 to 100 percent of Asian Carp from entering Lake Michigan.

Herbicides may not be sole cause of declining plant diversity (Science Daily): The declining plant biodiversity has often been blamed by herbicides, but other factors may be a cause. A study found that rare and common plant species had similar tolerances to three commonly used herbicides, which means they do not have a strong effect in shaping plant communities. During the time that herbicide use was on the rise, crop segregation and increased mechanical use were growing and diminishing habitat loss.

Report: Keystone pipeline would have minimal environmental impact (NBC News): A pipeline that would be used to carry crude oil from Canada to refineries in the United States was found to have minimal impact on the environment if it were to be constructed. There has been increased pressure on the president to approve the project, who will only do so if the project does not have a negative effect on the climate. Republicans, on the other hand, have been demanding for the approval of the project for a while because it will provide jobs, but climate and environmental concern are the main priority in the decision making process.

Senate Passes Long-Stalled Farm Bill, With Clear Winners and Losers (The New York Times): The Senate passed a farm bill on Tuesday that expanded crop insurance and other benefits for agriculture business. It is estimated to cut $17 billion from the budget of government spending over a decade. Anti hunger advocates and other critics, though, oppose the bill and say it would harm thousands of American households by causing them to lose money due to cuts in food stamps and they think that the industry does not need more support.
