Oil tainted lake a symptom, and symbol, of Venezuela's collapse

On the shore of Lake Maracaibo in northern Venezuela, people are removing polluted mud covered in oil. Fishermen, lament that fishing will end due to the lack of cleanup efforts.
Lake Maracaibo, South America's largest lake, has become a symbol of the decline of Venezuela's oil industry. Despite two decades of Chavism rule, environmental issues are missing from the political debate ahead of the July 28 elections.
