Man by his intelligence uses every possible way to alter the balance of the nature to satisfy his selfish motives. There are about 10 million different species of organisms in the biosphere. At present, because of human activities, the world may be losing up three species a day, and the rate is increasing, so inevitably some species are being lost before we even know they exist. Then they become extinct for ever; because it is not simply death –it is an end to birth. So it is a must to conserve the species.
Conservation can be described as an attempt by man to develop a way of life that does not disturb the balance of nature, and yet allows him to maintain all the advantages of modern civilization.
