Environment

"Everything that people can see around it is a part of environment"

Each and every thing is the part of environment and has a different role in the environment. Our environment is a carbon based system (Organic).

Earth is the place at which the life exist. The earth is covered by a layer of gases which is mostly Nitrogen and Oxygen the other gases like Carbon dioxide and others are in just a few amount. The earth surface is mostly covered by the oceans and the rest of the part is land on which the modern Civilization is spread out. The earth is a rotating heavenly body which is inclined twenty three and a half  degree. It has a moon because of which the high tide low tide comes in the oceans.The oceans have two types of life first is the life which is dependent on the sun light and the other is dependent on the energy which is produced by the condensed core which is very hot and in which the molten form of materials exists. The plants in the oceans having access to sun light makes food and gives oxygen using the minerals and water dissolved carbon dioxide which is a result of the break of calcium carbonate. The oxygen made by the plants underwater makes the life possible as we see in the present day either underwater or in lands. The food chain in the earth starts from the plants and algae which makes food from sun light which is the main source of our system. Plants are eaten by small living being in the water and in the lands this work is done by vegetarian animals. These living beings are eaten by bigger living beings and then after the death of the giant this is eaten by small beings which releases the unwanted material and that unwanted material is converted into beneficiary material for plant by micro organism. This is a cycle of living. In the tropical heat or cold the function of the system is unaffected by situation but adjusted by the creature.
