1. ENVIRONMENTAL PROBLEMS IN ASIA

2. Environmental Problems in Asia Two major factors: Unparalleled economic development of the different countries in Asia Incessant increase of human population

3. Desertification Salinization Alkalization Intensified use to meet food supply needed

7. Contamination Problems in waste disposal Rapid population growth

8. Land degradation AAZLINNOTISI SALINIZATION ZLAAKATNILOI ALKALIZATION NRDSCEIEIFIATTO DESERTIFICATION Remember SAD

9. Salinization and Alkalization When salts come to the surface of the land or are carried in by water When water well are overused, the water table lowers and saltwater or brackish water start to permeate Bangladesh

10. Desertification Transformation of fertile land into a desert through soil erosion or overcultivation If it persists  will bring about serious health hazards; food scarcity, dust storms China

11. Overgrazing

12. As the size of animal herds increases, more pressure is wielded on the grazing lands Iraq: sustains 11 million sheep which exceeds the lands’ grazing capacity

13. ZIIBRANNAUTO URBANIZATION

14. Urbanization in Asia Led to the proliferation of depressed or slum areas

16. SWEAT AISSODLP WASTE DISPOSAL

17. Problem on Solid waste disposal Two types of wastes: Domestic Industrial Health risks, degradation of the environment

18. Loss of Biodiversity Introduction of non-indigenous species of flora and fauna in a particular region Pollution of soil, water and air Rapid growth of the population Intensification of the use of land Deforestation Exploitation of natural resources ?

19. POLLUTION LOLOUNPTI

20. Pollution Air - sulfur & coal - Traffic in major cities (Beijing, Korea, etc.) - gas pollutants affect the quality of air - lead to respiratory diseases

22. Water Pollution Two most common water pollutants: Solid waste Untreated wastewater from industries and factories Marine Water: Oil spills Residues of pesticides Red tide  dinoflagellates  may lead to poisoning of people

23. Water Pollution Freshwater Pollution caused by rapid urbanization and industrialization Industrial effluents, heavy chemicals and solid wastes  directly released to inland bodies of water Mine tailings (rejected materials from mining processes) Siltation

24. Water Pollution Freshwater Siltation Accumulation of fine-grained sandy sediment carried by water  two main causes: 1. Deforestation 2. Soil erosion Tonle Sap

25. Clearing of forest trees Loss of natural habitat  flora and fauna endangered Causes of deforestation: Commercial logging Slash and burn agriculture Cutting down of trees for fuel wood and forest fires NEODFTESAROTI DEFORESTATION

26. North Asia: environmental problems Pollution: due to waste - radioactive uranium plants in Kazakhstan - waste dumped in rivers: threaten water source - extensive soil erosion Uranium radioactivity causes mutations and growth of cancer cells Uzbekistan’s water is under radioactive threat

27. The importance of ecological balance in asia
