Environment means all that surrounds us. It is a very complex and comprehensive phenomenon. It consists of the climate, geography, geology and all the natural resources that nature has bestowed upon us. Life is there because of our peculiar biosphere and ecosystem. There is life on this planet because of a certain balance between these various elements. Without this balance, our planet would have been just another sterile and lifeless planet revolving round the sun.
Our life depends on healthy and balanced environmental conditions. Our health, working habits, lifestyle, and behaviour, etc. are closely linked with all that surrounds us. The climate is an integral part of the environment. The varied climatic conditions on our planet have been responsible for all the variety that we have in our cultures, clothing, foods, festivals, and social customs, etc. The human population is scattered all over the world. But there are marked socio-cultural differences among the various races, groups, and countries because of different geographical and climatic conditions.
Existence on the earth presupposes maintenance of biodiversity and the preservation of the delicate balance between the various elements that constitute our environment, geographical conditions and climate. Preservation and protection of environment means the protection of the earth, its atmosphere, and its various vital resources. These are the essential ingredients of our life and existence, and should be kept alive, pure, vibrant and rich. Of late, it has been keenly felt that their depletion can prove disastrous. For example, the depletion of the ozone layer of our atmosphere has caused a huge hole in the sky, which is growing bigger and bigger with the passage of time. Consequently, the very harmful ultraviolet rays from the sun are reaching the earth. This hole
