BP's calamitous behavior in the Gulf of Mexico is the big oil story of the moment. But for many years, indigenous people from a formerly pristine region of the Amazon rainforest in Ecuador have been trying to get relief from an American company, Texaco (which later merged with Chevron), for what has been described as the largest oil-related environmental catastrophe ever. "As horrible as the gulf spill has been, what happened in the Amazon was worse," said Jonathan Abady, a New York lawyer who is part of the legal team that is suing Chevron on behalf of the rainforest inhabitants. Texaco operated more than 300 oil wells for the better part of three decades in a vast swath of Ecuador's northern Amazon region. Texaco came barreling into this delicate ancient landscape in the early 1960s with all the subtlety and grace of an invading army. And when it left in 1992, it left behind, according to the lawsuit, widespread toxic contamination that devastated the livelihoods and traditions of the local people, and took a severe toll on their physical well-being. The quest for oil is, by its nature, colossally destructive. And the giant oil companies, when left to their own devices, will treat even the most magnificent of nature's wonders like a sewer. But the riches to be made are so vastly corrupting that governments refuse to impose the kinds of rigid oversight and safeguards that would mitigate the damage to the environment and its human and animal inhabitants.
