Oil-Related Pollution in Venezuela Causes ◊One of the world’s leading producers of oil ◊Oil production has boosted economy Main source of income for many people Causes ◊One of the world’s leading producers of oil ◊Oil production has boosted economy Main source of income for many people
23
Effects… Oil production results in toxic waste, air pollution, & oil spills which damage the environment. hurts the ability of fishermen to earn a living Oil businesses have damaged Lake Maracaibo (largest lake in South America).

Lake Maracaibo ◊Large amounts of oil have been removed from the area so the land is changing. eastern shore of the lake is dropping about three inches a year government is having to take precautions to keep water from flooding into nearby towns ◊Large amounts of oil have been removed from the area so the land is changing. eastern shore of the lake is dropping about three inches a year government is having to take precautions to keep water from flooding into nearby towns
