In April 2010, an oil rig exploded in the Gulf of Mexico. Millions of gallons of oil leaked into the Gulf, devastating wildlife. Scientists tried to clean up the spill in a variety of ways. One approach involved the use of oil-eating bacteria. However, scientists were divided on its effectiveness. Some maintained that the bacteria were "fairly fast" in cleaning the spill. Officials reported that the Gulf would make a full recovery by 2012. Yet Samantha Joye, a marine scientist, disagreed. She conducted a study of the sea floor. She found that the bacteria had cleaned only 10 percent of the oil. She reported that the Gulf would take many years to recover.

Finding a new animal species is always exciting for scientists. However, it is even more exciting when a new species finds the scientists. That is what happened to a team of researchers camping in the Foja Mountains of Indonesia in late 2008. While eating lunch, one scientist looked down. He saw a little frog jump onto a nearby rice sack, and he caught it with his hands. The creature turned out to be a new species of long-nosed frog. The scientists named the species Pinocchio.

In 2011, a government commission in Chile approved a $7 billion project. The money was for the construction of five dams across two rivers. Supporters of the dams said that Chile needed them. The dams would help the country grow out of poverty. Opponents, however, pointed out that the dams would have damaged untouched wilderness areas. In 2012, the Supreme Court in Chile blocked the project. The court wanted more research into the dams' impact. Opponents of the dams believe that Chile should develop other forms of energy. The year-round sun of its northern deserts is ideal for producing solar power. Chile could also harness wind power from the gusts along its long Pacific coast.
