Destroying forests.Cutting down forests damages thousands of acres of land every day. The soil can easily be blown away and there is less soil. Even if new tree are planted they cannot bring back the old forest that was the part of a complex ecosystem that cleaned the air, trapped flood waters and made a home for much wildlife.

Water pollutionWater pollution is very serious, too. Ugly rivers of dirty water polluted with factory waste, poisoned fish are all-round us. And polluted air and poisoned water lead to the end of the civilization. So, nowadays a lot of dead lands and lifeless areas have appeared. Because our actions and dealings can turn the land to a desert 

Air pollution Air pollution is one of the most burning problems of nowadays. Now millions of chimneys, cars, buses, trucks all over the world exhaust fumes and harmful substances into the atmosphere. These poisoned substances pollute everything: air, land, water, birds and animals. So, it is usually hard to breathe in the large cities where there are lots plants. Everything there is covered with soot and dirt. All these affect harmfully. Every year the atmosphere is polluted by about 1000 tons of industrial dust and other harmful substances. Big cities suffer from smog. Cars with their engine have become the main source of pollution in industrial countries

Global warming.Human activity has been increasing the concentration of greenhouse gases in the atmosphere (mostly carbon dioxide from combustion of coal, oil, and gas; plus a few other trace gases.Global surface temperatures have increased about 0.6°C (plus or minus 0.2°C) since the late-19th century, and about one half degree F (0.2 to 0.3°C) over the past 25 years (the period with the most credible data).

 

Waste and chemicalsMost cities produce a lot of waste every day. If it is just thrown away or even dug up, it may be around for decades and could even release dangerous chemicals into the soil. These poisons can threaten the lives of the people that living or working by.
