negative effects such as air and water pollution, deforestation, desertification and land degradation. I think that the worst problems now affecting Mongolia are pollution and deforestation. People say that Mongolia was called ‘A land of blue sky’ in 1970s. Nowadays, air pollution is one of the facing issues to our country, especially the capital city. Thermal power plants, ger district, and old vehicle smoke are the main factors to pollute air. Air pollution in UB is increasing year after year.

Industry is one of the greatest source of pollution, accounting for more than half the volume of all water pollution and for the most deadly pollutants. Some manufacturing facilities use huge quantities of freshwater to carry away wastes of many kinds. The waste-bearing water, or effluent, is discharged into streams, lakes, or oceans, which in turn disperse the polluting substances. The pollutants include grit, asbestos, phosphates and nitrates, mercury, lead, caustic soda and other sodium compounds

Use of renewable energy technologies for desalination Wang Shuxian z3452701 Abstract Only about 0.25% of total fresh water, which is only 3% of total water in global world, could directly supply for the most needs of human beings and animals. Another significant impact is due to rapid population growth, causing severe fresh water scarcity. Other factors include rapid industrial growth, industrial wastes and sewage discharged and climate change. It would be feasible to overcome the water scarcity
