Long Answer questions (120-150 words)

LA 1. What change in the perception of human being has been brought about by Green Movement? Please elaborate.

Answer: The green movement has gripped imagination of human being  completely and quickly.

We have shifted from mechanistic view to a holistic and ecological view of the world. This shift in our perception is as revolutionary as the discovery of Copernicus. He had discovered that planet and satellites moved around the Sun.

Human beings have now become conscious to the thought that the Earth itself is a living organism and we are merely a part of it. The earth has its own metabolic needs and we need to ensure its availability.

Human being have realised importance of forests and the four principals of ecological balance. There are now efforts to protect and conserve these aspect though these may not be sufficient.

Human being have realsied the ill effect population explosion can have on environment. More people will mean greater requirement of consumption of natural resources.

Thus the perception of human beings has taken a turn for the good.



LA 2. What ill effect over exploitation of forest can cause? Please explain in the context of lesson ‘The Ailing Planet’.

Answer: It has been said that forests precede mankind and deserts follow. It signifies that forest is important for development and sustenance of mankind.

Forests keep environment cool. It brings rain to the earth. It is home to millions of species that maintain ecological balance.

Tropical forests are now eroding at a rate of forty to fifty million acres per year. The cost of firewood has been increasing disproportionately. It is feared that cost of fire wood could soon be more than the coast of food itself. The growing use of dung for burning has deprived soil of natural fertilizer. This also a cause of decrease in vegetation on earth.

Decrease in forest cover has already caused global warming. Many species have become extinct and many more are on the verge of extinction. Soil erosion has become quite common.

Thus over exploitation of forest is very harmful to human being.



LA 3. In the context of lesson ‘The Ailing Planet’ please explain the quote ‘Forests precede mankind, deserts follow?

Answer: The earth had come into existence much before human beings had evolved. First of all vegetation developed – on the ground and in the water. Forest cover grew thicker and thicker. Gradually several micro-organism and species developed. It was much later that the human being evolved on earth. So forests preceded mankind.

Thus man got forest as inheritance from Mother Nature. Initially his needs were limited. The natural cycle of earth compensated more than the man took from it. Gradually needs of mankind grew exponentially. Large areas of forest were cut for farming and fire wood. Other natural resources too were exploited for his comfort and pleasure.

Population explosion started putting extra burden on natural resources. A quick depletion resulted into global warming and rapid reduction in areas of forests. Rainfall has declined. The combined effect resulted into increase in desert area.

Thus the statement is justified in the context and content.


LA 4. Do you feel title of the lesson ‘The Ailing Planet’ justified? Please explain.

Answer: The title of the lesson is very much justified.

Author talks about the poor condition of four principals of ecology – fisheries, forests, cropland and grassland. The over-exploitation of these resources has caused a gradual depletion of these resources.

Population explosion has put lot of pressure on natural resources. More people does not mean more workers but it means more number of people without work. It is feared that soon the cost of firewood may be more than the cost of food itself.

Rate of depletion of forest is increasing day by day. Efforts for reversing the damage either do not exist or are grossly insufficient. Global warming is increasing. Soil, air and water pollution is increasing. Industrial pollution is also increasing.

Thus the ecological balance of the Earth is in a critical condition. So the title of the lesson is justified.
