Long Answer Questions
Q1. How has the growth of world population affected the environment? Support your answer with suitable arguments?
Ans. The author Nani Palkhivala enumerates some alarming statistics to suggest how the growth of world population has tremendously affected the environment. The population which took a million years to reach the first billion took just another hundred years to reach the second billion. Another century passed it and reached the alarming figure of 3.7 million. Presently it is over 6 million and there is a huge demand on resources, natural or man-made. The resources worldwide are under a lot of stress and pressure. The four principal biological systems i.e. fisheries, forests, grasslands and croplands which form the foundation of the global economic system and provide raw materials to the industry are facing a lot of stress. The human demands on these systems are increasing at a rapid speed. Hence, sustainability and productivity are both hampered. When this happens, fisheries collapse, forests disappear, grasslands become wastelands and croplands deteriorate. The need of the hour is to become sensitive towards the needs of the environment to get affected; we will leave behind nothing but an ailing planet for our future generations.
Q2. We have not inherited this earth from our forefathers; we have borrowed it from our children. Discuss.
Ans. Earth’s resources are limited and will not last forever. In the twentieth century, there has been a revolutionary change in human perception. We cannot take the planet for granted. We are mere custodians. We have to take a holistic view of the very basis of our existence. The earth is a living organism of which we are parts. It has its own metabolic needs to stay alive and must be respected and preserved for the future generation. What is required is sustainable development that meets the needs of the present without compromising the destiny of future generation. There are four biological systems, namely fisheries, forests, grasslands and croplands. They form the foundation of the global economic system. They supply us food and raw materials for industry. In larger areas of the world, these systems are reaching unsustainable levels. Their productivity is being damaged. The growth of world population is another factor distorting the future of our children. Development is not possible if population increases. In this era of responsibility towards our future generation, population must be controlled. Industries must become environmental friendly. Now many industrialists, politicians and writers have realized their responsibility in preserving the non-renewable natural resources for the future generation.
