Darwin Calero is sufering from cancer after working on a oil field in a oil-contaminated community near Lago Agrio. The Ecuadorian Amazon is suffering a public health crisis of immense proportions. The root cause of this crisis is water contamination from 40 years of oil operations. The oil infrastructure developed and operated by Texaco had utterly inadequate environmental controls, and consequently Texaco dumped 18 billion gallons of toxic wastewater directly into the region's rivers. The contamination of water essential for the daily activities of thousands of people has resulted in an epidemic of cancer, miscarriages, birth defects, and other ailments.
