4) Oil Pollution caused by oil spills from tankers and oil from ship travel. Oil does not dissolve in water and forms a thick sludge. 5) Burning fossil fuels into the air causes the formation of acidic particles in the atmosphere. When these particles mix with water vapor, the result is acid rain. 6) An increase in water temperature is caused by global warming and thermal plants that use lakes and rivers to cool down mechanical equipment. CAUSE OF MARINE POLLUTION Land-based activities Sea-based activities Volume of vessel traffic and off-shore oil and gas activities are increasing Primary concern in marine pollution - operational, accidental or deliberate discharge of oil or mixture containing oil by ships particularly oil tankers traversing the Straits of Malacca and South China Sea.

The low oxygen levels are not able to support most indigenous organisms in the area and therefore upset the natural ecological balance in rivers and lakes. 5

Mercury has been found to interfere with the development of the nervous system in fetuses and young children. 5) Ecosystems are destroyed by the rising temperature in the water, as coral reefs are affected by the bleaching effect due to warmer temperatures. Additionally, the warm water forces indigenous water species to seek cooler water in other areas, causing an ecological damaging shift of the affected area. 7
