Oil Pollution When it comes to mixing oil and water, oceans

suffer from far more than an occasional devastating spill. Disasters make headlines, but hundreds of millions of gallons of oil quietly end up in the seas every year, mostly from non-accidental sources .

The graph below shows how many millions of gallons of oil each source puts into the oceans worldwide each year

Sources of Oil Pollution

Down the Drain: 363 Million Gallons

Used engine oil can end up in waterways. An average oil change uses five quarts; one change can contaminate a million gallons of fresh water. Much oil in runoff from land and municipal and industrial wastes ends up in the oceans. 363 million gallons

Road Runoff Every year oily road runoff from a city of 5 million could

contain as much oil as one large tanker spill

Facts Lake Maracaibo is South America’s largest lake

The lake and its small basin sit on top of a vast reservoir of buried oil deposits, first tapped in 1914.

Venezuela is now the world’s fifth largest oil producer.

The narrow strait has been deepened to allow ocean-going vessels access to the lake for oil transport.

Lake Pollution causes Shipping is one of the main sources of pollution in the

lake; pollution enters the lake when ships dump ballast and other waste.

Other sources of pollution to the lake include underwater oil pipeline leakage, untreated municipal and industrial waste from coastal cities, and runoff of chemicals from surrounding farm land. Deepening the narrow channel for shipping has also allowed saltwater intrusion into the lake, negatively affecting lake life.

Lake Maracaibo – Oil Pollution Between 1996 and 1997 Lake Maracaibo saw one oil

related accident every 40 days

On May 15th 1997 boats blocked the channel that leads to Maracaibo in protest to the oil companies constant pollution of the lake

Oil wells leaked oil into the lake for weeks before discovered

Oil Slick in Lake Maracaibo An oil slick, likely related to bilge pumping, can be seen as a

bright streak northeast of El Triunfo in this satellite image from February 23, 2007.

Oil Pollution’s Effects

Air Pollution in Mexico City Visibility due to air pollution has dropped from 100 km

to 1.5 km

Many have irritated eyes or constant headaches due to pollution

Pollution is stronger in the summer months

Caused by overcrowding, industrialization, vehicle emissions and the city’s location

Causes of Air Pollution in Mexico City Overcrowding

Industrialization

Vehicle Emissions

Location

Driving Restrictions In an effort to reduce car emissions in Mexico City

driving restrictions have been placed on the people. Monday: no driving if license plate ends with 5 or 6.

Tuesday: no driving if license plate ends with 7 or 8. Wednesday: no driving if license plate ends with 3 or 4. Thursday: no driving if license plate ends with 1 or 2. Friday: no driving if license plate ends with 9, 0 or a letter. Saturday and Sunday: All vehicles may be driven.

Results of Acid Rain

Brazilian Rain Forest Every second we lose the area equivalent to two

football fields

Every year that equals twice the size of Florida

With further destruction we could lose half the animals and plants on earth

20% of the world’s oxygen is produced in the rainforest

Results of Air Pollution Damages vegetation

Harms atmosphere

Pollution is so bad that it can lead to sickness or premature death

Many have irritated eyes or constant headaches due to pollution

Acid rain damages monuments
