"Earth - the only habitable planet known to mankind so far, has been sustaining all life on it through a free ecosystem facility fulfilling our need for air, water, natural food, fibre and shelter, selflessly. Comprised of diverse ecosystems that demonstrate a delicate balance between each component viz: atmosphere, hydrosphere, biosphere, cryosphere, lithosphere the earth systems are delicately balanced on each other. Man on the other hand has played havoc - indiscriminately burning fossil fuels, cutting forests, polluting water sources, excavating for mining and emitting chlorofluorocarbons (CFCs) and other poisonous gases into atmosphere accelerating the process of warming and creating holes in the safety curtain provided by nature in the atmosphere. While appreciating the need for development, it is argued by environmentalists that the Earth has physical and biological limits and it is of utmost importance that these limits are honoured. The Earth environment is required to be shielded from hazardous anthropogenic interference, maintaining a balance between utilisation of natural resources and preservation of the earth system. From the onset of industrialisation there has been an exacerbating pressure on the land and resources of the earth. The continue
Antarctic, the cold oceans surrounding it and the greater parts of Arctic are often conceptualised as the 'common heritage of mankind' - most enchanting, picturesque and pristine - sustaining the complex ocean-atmosphere coupled system of our planet and thereby ensuring the sustenance of life itself. While appreciating the need for development, it is argued by environmentalists that the Earth has physical and biological limits and it is of utmost importance that these limits are honoured.
