A living Organism cannot live by itself. Organism interact among themselves. All organism such as plants, animals and human beings , as well as the physical surroundings with whom you interact, form a part of the Environment are dependent upon each other.Thus, they maintain a balance in nature.
Human beings are the only organisms who try to modify the environment to fulfill their needs. Their acts have often been disturbed the links and balance of the environment . This Environmental imbalance give rise to various Environmental problems.
Some of the environmental problems are pollution. Soil erosion , extinction of species , deforestation, thinning of ozone layer and Global Warming.
Pollution
Environmental pollution is defined as the undesirable change in physical, Chemical and biological Characteristics of our air, land and water.
Types of Pollution
When we hear the word pollution the first thing that comes into our mind is Exhaust out of Automobile and Industries but it’s not all.
Pollution is classified in three types:
These are 1) Air Pollution 2) Water Pollution and
3) Soil Pollution or Land Pollution
Air Pollution
Sources of air pollution are grouped under
1) Natural 2) Man Made
Natural Sources of air pollution are forest fires, ash from smoking volcanoes, dust storm and decay of organic matters.
Man Made sources are population explosion, deforestation, urbanization and industrialization. Many activities releases several pollutants such as Carbon monoxide, hydrocarbons, oxides of nitrogen, lead, arsenic, asbestos, radioactive matter, and dust.
Oxygen Required for Combustion
For 1Ton oil 10.300m3
For 1Ton Coal 1, 15,000m3
For 1Ton Cooking Gas 15,600m3
Conservation and Protection of Environment
The term conservation of environment relates to activities which can provide individual or commercial benefits, but at the same time prevent excessive use of leading to environmental damage.
Conservation may be distinguished from preservation , which is considered to be “maintaining of nature as it is , or might have need before intervention of either human beings or natural forces.
It is necessary to conserve and protect our environment. Following practices help in protecting our environment.
1. Rotation of Crops
2. Judicious use of fertilizers, intensive cropping, proper drainage and irrigation.
3. Treatment of sewage, so that it does not pollute the rivers and other water bodies.
4. Composing organic solid waste for use as manure.
5. National parks and conservation forests should be established by the government.
6. Harvesting of Rain water.
