3. Polluted Oceans and Seas Are all the seas and oceans polluted? Some seas, like the Mediterranean Sea, are more polluted than others because they only have a very small outlet into the ocean and the pollutants stay in the water (basin). The oceans that are the main seaways of oil tankers are sometimes very polluted.

4. Polluted Oceans and Seas The seas near the north pole and the south pole are less polluted because there are less factories and oil tankers near them. The melting icebergs also add a lot of water to the multitude and the pollutant becomes less harmful to the creatures and plants of the sea.

6. Polluted Oceans and Seas Here are some of the reasons: Countries let sewage flow into rivers and seas Factories pour chemical waste into them - emissionsemissions Oil tankers spill a lot of the oil they carry, especially if there are accidents. Pesticides that are washed from the soil by rain and floods flow into the seas. People throw all sorts of garbage into the sea (plastic bottles, bags, tyres, metal).all sorts Why are the seas polluted?

10. Polluted Oceans and Seas Who suffers when the seas are polluted? People suffer because many beaches are polluted and they cannot use them. People suffer because they get sick. There is less and less food that lives/grows in the sea like: fish, seafood, seaweed.

12. Creatures that live in the sea suffer/die because of the chemicals that harm them and also because a lot of their food (the food chain) is being destroyed by pollutants. Many plants and corals are destroyed by the chemicals. Many sea birds and other animals die or get covered in oil when a tanker causes a spillage of oil into the sea.

14. Polluted Oceans and Seas What can be done to clean the seas? Fines should be put on countries and factories that pollute the seas. There should be less tankers plying the seas and more pipe lines built to carry oil from one country to another. Counties should be encouraged to use more solar energy Farmers must use less pesticides. They should be encouraged to use organic agriculture.
