Concept of caring for Earth

The physical features of the earth are different at its various parts. The earth is surrounder by air. It has been a living planet because of the availability of oxygen, water and land. These factors have contributed to the formation of a natural environment. There is also variation in the natural environment in the earth. Because of the variation fo natural environment there is a diversity in animals, birds and organisms. The spheres of the earth are lithosphere, atmosphere, hydorsphere and biosphere. A close link exists among these spheres. Disturbance in one of the spheres affects another. It causes imbalance in the natural environment. It deteriotes the various natural cycles such as water cycle, cycles of gases (oxygen, nitrogem, etc). the change in these aspects disturbs the animals birds and many living organisms.

The caring for the earth means to conserver all the physcal and biological aspects fo the earth. Its objective is to provide and opportunity to continue the life of all the living beings. This will take place only if all the elements of sphere either living of non-living are properly protected. There is need of conservation and promotion of all spheres: lithosphere, hydrosphere, atmosphere and biosphere.
