THINK GREEN,LIVE GREEN

We are now confronted with serios enviromental problems.The best way to fight them is by knowing what causes them and to figure out the best comprimise solution for the earth as well as for the humans.

population growth

The major cause of most environmental problems is the rapidly growing human population, now at 6 billion (2000 estimate) people worldwide. A quarter of a million babies are born each day-90 million each year. In another 50 years, the population will grow to about 9-10 billion. Meeting the basic needs of all these people- food, housing, heat, energy, clothing, and consumer goods-places tremendous demands on the earth's natural resources Without technological and land-use changes, in addition to population-control measures, the demands are bound to grow. Industrialized countries, with higher living standards and greater numbers of cars, produce far more air pollution and greenhouse gases than developing countries. Developed countries also contribute to overfishing and deforestation .

But these countries can reduce serious environmental hazards by using technology such as smokestack scrubbers, emission systems, and waste-water treatment plants. Although developing countries consume a far smaller percentage of the world's resources per person, the sheer numbers of people can quickly deplete soil, forests, and waterways.

air pollution

Air pollution is one of the most pervasive enviromental problems because atmospheric currents can carry contaminated air to every part of the globe. Most of the air pollution gases come from vehicle motors and power plants that burn oil and coal to produce the energy needed for industry and consumer use. Carbon dioxide and other harmfull gases have a bad influence on our health and are also leading to the greenhouse effect. Sulf dioxide,nitrogen dioxide ,once pumped into the atmosphere will combine with clouds creating the acid rains. The ozone layer is also...
