Understanding The Text

1. Locate the lines in the text that support the title ‘The Ailing Planet’.


The following lines in the text support the title ‘‘The Ailing Planet’’.
(i) ‘‘Are we to leave our successors a scorched planet of advancing deserts, impoverished landscapes and ailing environment?
(i) A three-year study using satellites and aerial photography conducted by the United Nations, warns that the environment has deteriorated so badly that it is ‘critical’ in many of the eighty-eight countries investigated.

2. What does the notice ‘The world’s most dangerous animal’ at a cage in the zoo at Lusaka, Zambia, signify?


According to the notice at the Lusaka zoo in Zambia, ”The world’s most dangerous animals” is symbolic of the fact that man is solely responsible for all the deterioration of the environment and depletion of natural resources.

3. How are the earth’s principal biological systems being depleted?


Excessive use of the earth’s major biological systems is depleting them. Overfishing is common. Forests are cut to obtain firewood for cooking. Grasslands are dying and croplands are deteriorating.

4. Why does the author aver that the growth of world population is one of the strongest factors distorting the future of human society?


The world population has grown at a very fast rate. This is endangering the future of human society. It has put too much pressure on natural resources. Forests, fisheries, grasslands, and croplands have been depleted alarmingly. It will soon be impossible for human society to survive on this planet if we do not take determined steps to control population growth.

Talking About The Text

Discuss in groups of four

1. Laws are never respected nor enforced in India.


It is painful but true that laws are neither respected nor enforced in India. Our Constitution insists on the protection and improvement of the environment. The states have been given the responsibility of protecting forests and wildlife. Forests are being cut and illegal shooting of wildlife goes on. Similary, there are laws regarding abolishing casteism, untouchability and bonded labour. But these remain on paper. In actual life, these are never put into practice. Hence, it can be concluded that laws are neither respected nor enforced in India.

2. “Are we to leave our successors a scorched planet of advancing deserts, impoverished landscapes and an ailing environment?”


The apprehension is justified. Our resources are limited. If we continue to consume them indiscriminately, we will not be able to sustain them indefinitely. Fisheries, forests, grasslands and croplands form the basis of the global economic system. Increasing population has put severe strains on these resources. Excessive use has impairs their productivity. These systems have reached unsustainable levels in large areas of the world. Thus, fisheries will collapse, forests will disappear, grasslands will become barren, wastelands and croplands will lose their fertility, and the result will be terrible and disastrous. There is a possibility that the earth may become overheated in the future with increasing deserts, poor landscapes and ailing environments as a result of the destruction of forests.

3. “We have not inherited this earth from our forefathers; we have borrowed it from our children”.


There has been a change in people’s perception of the planet over the decades. Human perception has shifted to one that focuses on the whole world. The earth is a living organism with limited resources. These resources will not last forever. The earth has metabolic needs that must be met. The need of the hour is sustainable development which propounds the need of meeting the needs of the present generation without compromising with those of future generations. There is a need to curb our consumption of non-renewable resources. We should preserve natural resources and hand them over to future generations intact since they represent the real owners.

4. The problems of overpopulation that directly affect our everyday life.


Food, clothing, shelter and other basic human needs have assumed alarming propositions as a result of overpopulation. Fisheries, forests, grasslands and croplands are being severely impacted. Grasslands are becoming deserts as a result of the destruction of forests for firewood. Overpopulation hinders development and adversely affects the spread of education and health care. Artificial fertilizers have improved crop productivity. People with low incomes tend to beget more children, which ultimately leads to poverty. More children mean fewer workers and merely more people without jobs. Thus, overpopulation leads to unemployment. Overpopulation leads to insufficient public transportation. There are long queues everywhere. The result of overpopulation is deterioration of the environment and shortened lives.
