The Important of Environment for Us

If a person is sitting inside a room then all the things, either living or nonliving, that have surrounded him is counted as the environment of that room. It is same as this earth is full of living or non living organism which are the part of environment. Human, plants, animals, birds, weather, wind, sunlight, sand, soil, land, water, coal, wood, fuels, fire, minerals, etc are the parts of environment which are essential for existence of life on earth.

As we all know, this earth is made of four different spheres biosphere, lithosphere, atmosphere and hydrosphere in which hydrosphere is the largest part on earth among all. All the spheres contain some of the natural resources inside its category:

1. Atmosphere: Air, sunlight, weather, etc.
2. Lithosphere: Solid or rigid area of the earth, also we can say that the crust and the upper mantle of the earth like land.
3. Biosphere: Biosphere is the area or zone of earth where life exists in form of plants, animals, birds and human.
4. Hydrosphere: The largest portion (about 75%) of the earth area where water is found in form of oceans.

Life on earth is possible due to some kind of action and reaction between different kinds of resources that are available under environment.
