An increase in global surface temperature is likely to be 1°C by 2030 A.D. and 3°C before the end of the next century if green house gases are continued to be released at the current rate.

The earth is heated up by sunlight and some of the heat that is absorbed by the earth is radiated back into space. However, some of the gases (like C02) in the lower atmosphere, serving like glass in a green house, allow the solar radiations, but do not allow the earth to re-radiate the heat […]

Rain water harvesting is a technique of recharge of ground water by capturing and storing rain water. This is done by constructing special water-harvesting structures like dug wells, percolation, lagoon, check dams etc. Rain water harvesting is not only proving useful for poor and scantly rainfall regions but also for the rich ones.

Water being one of the most precious and indispensable resource needs to be conserved. The following strategies can be adopted for conservation. The following strategies can be adopted for conservation of water:

Availability of water in a given soil environment is a critical factor and is related to erosion, siltation, loss of plant cover and productivity. In India floods bring considerable damage resulting in loss of life and property each year. Due to floods, the plains have become silted with mud and sand that affect the cultivable […]

Energy is a essential need of a man where-ever he lives- urban of rural society. In urban areas the need of energy is increasing by leaps and bounds. Take the case of mega- urban dwelling places.

Continuous and persistent rise in system is known as sustainable growth It means continuous rise in the GNP of the country resulting into the rising trend in per capita income of the country.

The energy used in Giga (denoting factor of 109) Joules per capita in transportation is 2,103 in United States, 82 in Australia and 4 in Zimbabwe.

Unsustainable development or growth is one in which social issues of life do not progress in a healthy and ethical style.

Activities of man right from birth to death on this earth are deeply related to social issues. He while living in society cannot detach himself from social issues of life.

Waste Heat generation, which is dangerous to waters, can be controlled by transformation to normal temperature by the following methods:

Wastes are chemical by-products of an industry, a factory or a chemical plant. They may result from household activity/a hospital or a research laboratory.

Thermal pollution has become an increasing and the most current pollution, owing to the increasing globalization everywhere.

Soil is a very specific component of the biosphere as it is a natural geochemical sink for contaminants and acts as a natural buffer controlling the transport of chemical substances to the atmosphere, hydrosphere and lithosphere.

The polluted water can be detoxified and neutralized through treatment processes. The different treatment processes that control pollution are:

Water pollution can be classified according to type of pollutants and on the basis of sources of pollution
