ENVIRONMENTAL CHALLENGES The earth is the only living and breathing planet in our solar system. The life of fauna and flora as well the future of the human race would depend upon its health. However, rapid advancements in sciences, industry and nuclear armaments have led to considerable changes in the environment of this beautiful planet. There are many contributing factors that lead to ecological imbalances and environmental degradation. The major causes have been appended as follows: (A) Depletion of Forests The food chain depends upon the vegetation of the earth. Forests are an integral part of the vegetation. Man has cut down the vast forest reserves in the name of industrialisation and rapid urbanisation. Moreover the rural masses depend upon wood from the forests to keep their kitchen fires alive. The loss of forest cover has resulted in an unstable rain fall pattern. There is a reduction in annual rainfall in those areas where forest covers have been depleted. For example, poor or only moderate rain in the National Capital Region during June-September 1999, amply demonstrate that our rainfall patterns are no longer norm as they were a decade ago. Imbalance of proper supply of oxygen adversely affected all the living organisms. Air pollution has increased. Forest covers minimise soil erosion during floods and are also, a natural habitat for wild life. With the reduction in their size, the fertile land as well as wild life has been seriously affected. Several wild life species, like Dodo, have become extinct. The temperature in the forest covers has increased at an alarming rate. If afforestation measures are not taken around the globe, the posterity may hav e to pay heavily in terms of the costs of environmental degradation. (B) Ozone layer Ozone layer surrounds the atmosphere of the earth and protects us from harmful solar radiations. It also protects the earth from over- heating. However, Chloro Flouro Carbons (CFCs), Carbon Monoxide and other gases rise up in the atmosphere and form compounds with Ozone gas. Thus density of Ozone gas is reduced above the surface of the earth in the upper atmosphere. This phenomenon is termed asOzone Hole. This hole allows the harmful ultraviolet rays to pierce through the atmosphere and fall on to the surface of the earth. The earth gets heated up and the living beings are also exposed to these rays. If these unhealthy trends continued, then polar ice caps would melt which would eventually raise the ocean levels. (C)Floods Due to melting of the polar ice caps, the ocean levels would rise. So, low levels areas of the earth would be submerged. There would be small land left for us. For example, low lying areas would be submerged first due to the melting of polar ice caps. (D) Earthquakes If the poles of the earth get heated up due to Ozone holes, the ice would melt and would flow into the oceans. This would result in dangerous imbalances. So, the axis of the earth would shift. This could result in earthquakes. This natural disaster has already affected many nations; India, Iran, Mexico, the USA and China are examples;
