A pig, coated with a thick greenish film that grows on the lake, sniffs the ground while foraging near the shore of Lake Maracaibo, in Maracaibo, Venezuela, Thursday, Aug. 10, 2023. The pollution around the lake, one of Latin America's largest, is the result of decades of excessive oil exploitation on its bed, inadequate maintenance, and a lack of investment to improve an already obsolete infrastructure, according to environmentalists.
