Need For Conservation!!!

Since evolution of the man he started using resources in large amounts than required without knowing its importance now caused many environmental problems.

1.Over Exploitaion of non-renewable resouces endagered the very existence of the human beings.

2.Deforestation: The large-scale removal of forest, prior to its replacement by other land uses. This is causing natural imbalances viz., Global warming, Acid rains, unseasonal rains, etc the most important life supporting gas Oxygen O2 content is reduced.

3.Soil Erosion: Erosion is broadly defined as removal of sediment, rock, and soil from the landscape, resulting in the formation of new landforms and the lowering of the land surface, a process known as denudation.Agents of Erosion: Water, Wind and Ice are the major agents of soli erosion.Fertility of soil is lost due to erosion, which affects plant growth.Here Soil Erosion and Deforestation are Interlinked.

4.Ozone Layer Destruction: Ozone Layer:A rerion of gaseous layer, which is found at about 40 km above sea level that shields the Earth from the Sun’s harmful ultraviolet rays.

5.Harmful Radiation: This is caused due to testing of nuclear weapons which is carried out by many supreme powers and developing countries of the world to show their superiority in destructive technology.

There are many such problems which cannot be listed in this blog. Hence, to save our environment and our planet it ultimately becomes every individuals duty to conserve environment.
