 importance water.  sources of water pollution  water in Siberia  Methods of water protection from pollution  conclusion

."Water is more expensive than gold”

water is environment where chemical reactions take place.

 2/3 part of the Earth is covered with water.  Water is second important substance after oxygen on the planet.  Man can live only 3 days without water

Vantal

 temperature rise  decaying organic substances  waste of food industry  oil products  salts of heavy metals, chlorine, alkali, acid

 80% of deseases on the planet are caused by low quality and antisanitary condition of water

 Water is life, beauty and health  Water is the cradle of life.
