Ecuador's President Rafael Correa uses a stick to measure how deep the area is, in the Aguarico 4 oil field where a sign reads in Spanish "Danger. Contaminated area" in Ecuador, Tuesday, Sept. 17, 2013. Correa visited the site to call attention to oil contamination in Ecuador's Amazon region. Earlier this year, Ecuador awarded a $19 billion judgment to the residents of this area for Texaco's contamination of this rainforest between 1972 and 1990. But Chevron Corp., which bought Texaco in 2001, said it won't pay because it says Texaco dealt with the problem before it was bought. (AP Photo/Dolores Ochoa)

A woman gathers plants along the banks of the Mekong River while a child plays in the background.
