ENERGY RESOURCES Energy is defined as ‘the capacity to do work’. Sun is the primary source of energy. Joule is the standard unit of energy in SI units. Energy utilization is an index of economic development‚ which does not take into account of ill effects/damage on to environment. From 1900 to 2000 population increased by 3 times while energy consumption by 14 times! Energy Resources All energy sources ultimately come from the sun‚ the moon or the earth.

The causes of pollution Pollution is the release of harmful environmental contaminants. The main air pollutants are carbon monoxide‚ lead oxides‚ sulfur dioxide and nitrogen oxides. The principle causes of pollution are exhaust pipes from motor vehicles‚ smoke released by factories and moreover‚ industrial plants burn coal and oil‚ which contain sulfur. New inventions and processes have been continuously developed to improve our way of life; such developments are called technological

availability of fresh water and its unequal distribution make water pollution a matter of great concern. Water pollution is generally localized and confined‚ making it more severe. The pollutants undergo many reactions and can become hazardous. 70 % of India’s fresh water is polluted‚ including several high altitude lakes. While water pollution is easier to study and manage‚ its control is highly complex and very costly. Water pollution is defined as presence of any foreign substance (organic‚ inorganic

The Water Pollution on Our Earth If we watch news now‚ sometimes they talk about our environment. They say that our environment is very worrying and needs the attention from us. One of our environments is water. Water is a vital necessity for us to fulfill the daily needs such as cooking‚ bathing‚ washing and the others else. We usually hear that some big city have a problem with their water‚ some area in many country occur drought‚ and many people compete to get clean water. We often ask in our

While rapidly growing air pollution in China brought on by harmful factory production and out dated fueling methods has created an abundance of health inequalities as well as permanent damage to the surrounding ecosystems‚ the solution to these issues prove difficult to solve.

Noise Pollution Noise pollution is not a necessary price to pay for living in an industrial society. Much can be done to reduce the severity of the problem. For example‚ vehicles and other machines can be built to produce less noise. Four-cycle engines can replace much noisier two-cycle engines in such products as lawnmowers‚ motorboats‚ and jet skis. Labels that indicate the noise levels of appliances and tools can help consumers avoid noisy products and choose quieter alternatives. Even

The two policies that are mostly used to reduce pollution are the taxation of the pollution producers (Pigovian tax) and standards-change approaches. The Pigovian taxes are usually generally levied as an excise tax‚ which will raise the price of the goods produced. This causes the company to produce less which in turn lowers pollution. The standards-charge approach is to tax the pollution directly. The government determines the level of pollution that it thinks is appropriate‚ and then will charge

The role of urban heat islands and air pollution‚ PM2.5 and ozone‚ on human health is beginning to emerge. Lack of green space may have psychological effects for urban dwellers.
