Unless death rate rates rise sharply, world population may reach 8 billion by 2025, 10-11 billionby 2050, and 14 bilion by 2100 . To sustain that many of people, the environment has already paid off. Population has a great impact on the environment. Deforestation, agricultural activities, and enviromental pollution, are either entirly or partly caused by the impact of human population. In th!

In this process, about 6000 tonnes of exhaust gases rush up the flue every hour, containing 1200 tonnes of carbon dioxide, 200 tonnes of steam and about 30 tonnes of finely powdered ash.

Our Environment, Mitchell Beazley Publishers, London. But nevertheless, most forms of energy we consuming today, have different levels and ways impact on our environment.

In the final stage in a slow and insidious process of land degradation and erosion, is desertification which starts with the loss of vegetative cover and ends with the destruction of the the soil’s fertility and its transformation into barrin desert.
