9. a major problem in developing countries as many people in these areas don’t have access to sanitary conditions and clean water. In developed countries, sewage often causes problems when people flush chemical and pharmaceutical substances.

10. Wastewater often contains faeces, urine and laundry waste and can contaminate the environment; causing diseases such as diarrhoea. Sewage carries harmful viruses and bacteria into the environment causing health problems.

11. Contaminated waste water pours into a public canal in Thailand from a industrial treatment plant.

12. MARINE DUMPING

13. Litter items such as ring packaging can get caught in marine animals and may result in death. Different items take different lengths of time to degrade in water.

15. Industrial Water

16. Industry produces pollutants that are extremely harmful to people and the environment.

17. Many industrial facilities use freshwater to carry away waste from the plant and into rivers, lakes and oceans.

18. NUCLEAR WASTE

19. produced from industrial, medical and scientific processes that use radioactive material. Nuclear waste can have detrimental effects on marine habitats.

21. OIL POLLUTION

22. from oil spills routine shipping run-offs and dumping

23. They cause a very localized problem that can be catastrophic to local marine wildlife. Oil forms a thick sludge in the water. This suffocates fish, gets caught in the feathers of marine birds stopping them from flying and blocks light from photosynthetic aquatic plants.

25. Underground storage leakages

26. tanks with, at least, 10% of its volume underground, they often store substances such as petroleum

27. ATMOSPHERIC DEPOSITION

28. caused by air pollution. In the atmosphere, water particles mix with carbon dioxide sulphur dioxide and nitrogen oxides, this forms a weak acid. When it rains the water is polluted with these gases, this is called acid rain. It pollutes marine habitats and aquatic life is harmed.

30. ACID RAIN EFFECTS acid rain harm buildings, it damages trees and kills aquatic life and other organisms.

37. EUTROPHICATION

39. Phytoplankton grows and reproduce more rapidly, resulting in algal blooms. the environment becomes over-enriched with nutrients

40. Algal blooms disrupts normal ecosystem functioning: algae use up all the oxygen in the water, they also block sunlight from photosynthetic marine plants under the water surface; some algae even produce toxins that are harmful to higher forms of life
