1. About the Article
Author: Nani Palkhivala, an Indian jurist, economist and writer.
Original source: The Indian Express, 24 November 1994.
Subject: The declining health of the earth and the need for people, governments and industries to protect the environment.
Central argument: Human beings must stop treating the earth as an unlimited storehouse of resources. We are part of a living ecological system and must use its resources responsibly so that future generations can also live well.
2. Complete Summary
Nani Palkhivala begins by describing the Green Movement as one of the fastest-growing movements in world history. The first nationwide Green Party was founded in New Zealand in 1972. The movement helped people change the way they looked at the earth.
Earlier, many people viewed the world in a mechanical way, as if it were an object or machine that existed for human use. The newer holistic and ecological view sees the earth as a living organism. Human beings are only one part of this vast system. Like a living body, the earth has its own needs and natural processes. These must be respected and protected.
The author says that the earth is like a patient whose health is declining. People have a moral duty to act as its stewards and trustees for future generations. This duty is linked to sustainable development: meeting present needs without reducing the ability of future generations to meet their own needs.
To explain human responsibility, Palkhivala refers to a cage in the Lusaka Zoo in Zambia. A notice calls the world's most dangerous animal. Inside the cage is a mirror. Visitors see themselves. The message is that human beings, through careless actions, can cause great harm to the planet. They must move from domination of nature to partnership with it.
The article then discusses the earth's four main biological systems: fisheries, forests, grasslands and croplands. These systems provide food and many raw materials. They are being used faster than they can recover. Overfishing damages fisheries; forests are cut for fuel; grasslands become barren; and croplands lose productivity. The destruction of tropical forests also threatens many species.
Palkhivala draws attention to the loss of forests around the world and in India. He refers to Article 48A of the Indian Constitution, which directs the State to protect and improve the environment and safeguard forests and wildlife. He is critical of the gap between laws and their enforcement. He also cites a United Nations study which found that environmental conditions were critical in many of the countries it examined.
The article next discusses population growth. Palkhivala uses figures from the 1994 article to show how quickly the world population had increased. He argues that rising population puts pressure on food, land, water, jobs and other resources. He supports voluntary family planning and says that better income, education and health help reduce fertility. His point is that development and population planning must go together.
In the closing section, the author says that concern for the planet has become a responsibility shared by all humanity. He calls this new outlook the Era of Responsibility. Industry must also take part by improving its environmental performance. The article ends with two memorable ideas: Margaret Thatcher compares human life on earth to a tenancy that must be properly maintained, while Lester Brown says that the earth is borrowed from our children. Both quotations remind us that we must pass on a healthy planet to those who come after us.
3. Section-wise Explanation
A. The Green Movement and a new way of thinking
The Green Movement made environmental protection a worldwide concern. The founding of the first nationwide Green Party in New Zealand in 1972 is given as an important event. Palkhivala compares the change in human thinking to the revolution brought about by Copernicus. Just as Copernicus changed the accepted view of the universe, the ecological view changes the way people understand their place on earth.
B. The earth as a living organism
The earth is not merely a collection of materials for human use. It is a living system with connected parts and natural processes. If one part is damaged, other parts may also suffer. The phrase “patient in declining health” presents environmental damage as an illness that needs attention.
C. Sustainable development
The World Commission on Environment and Development popularised the concept in 1987. It means using resources to meet present needs without taking away the ability of future generations to meet theirs. Development should improve human life without destroying the natural systems on which life depends.
D. The mirror in the Lusaka Zoo
The mirror makes visitors face their own responsibility. Humans are called the most dangerous animal because their actions can destroy habitats and natural resources on a large scale. The author does not ask people to dominate nature. He asks them to work in partnership with it.
E. The four biological systems
Lester R. Brown identifies fisheries, forests, grasslands and croplands as the earth’s principal biological systems. They support the global economy by supplying food and many raw materials. When people take more than these systems can renew, their productivity falls.
F. Forest destruction and the Indian situation
The author describes the cutting of forests for firewood and the loss of tropical forests. He also points to the harm caused when dung is burnt as fuel instead of being returned to the soil. In India, he refers to Article 48A and criticises weak enforcement of environmental laws. The statistics he quotes describe the situation as reported in 1994.
G. Population growth
Population growth increases pressure on natural resources and public services. The author connects poverty, low levels of education and poor health with high fertility. He argues for voluntary family planning, not forced sterilisation. The article’s phrase “development is the best contraceptive” expresses his view that social and economic progress can help lower fertility.
H. The Era of Responsibility
The article ends by asking individuals, governments and industries to accept responsibility. The environment is not a concern for one country alone. It affects the survival of the whole planet. The final quotations present the earth as something held in trust for future generations.
4. Mechanical View and Holistic-Ecological View
| Mechanical view | Holistic and ecological view |
|---|---|
| Sees the earth as an object or machine. | Sees the earth as a living, connected system. |
| Places human beings above nature. | Sees human beings as one part of nature. |
| Encourages use and exploitation of resources. | Calls for care, balance and responsible use. |
| Often ignores long-term effects. | Considers the needs of future generations. |
| Separates the parts of the world. | Sees the world as an integrated whole. |
In simple words: The mechanical view treats nature as something to be used. The holistic view treats nature as a living system of which humans are a part.
5. The Four Principal Biological Systems
| System | How it is damaged | Result |
|---|---|---|
| Fisheries | Overfishing and excessive demand for fish. | Fish stocks decline and fisheries may collapse. |
| Forests | Cutting trees for firewood and other uses. | Loss of habitats, species and forest cover. |
| Grasslands | Overuse and poor management. | Grasslands may turn into barren wastelands. |
| Croplands | Unsustainable pressure on agricultural land. | Soil and land productivity decline. |
These systems provide food and raw materials. Their health is necessary for the health of the global economy and human society.
6. Population Growth and Development
Palkhivala argues that rapid population growth puts pressure on the earth’s resources and makes it harder to provide basic needs. He links lower fertility with rising incomes, wider education and better health. He supports voluntary family planning and rejects compulsory sterilisation.
The statement “development is the best contraceptive” means that improvements in income, education and health can help families choose to have fewer children. It does not mean that development alone solves every environmental problem.

9. NCERT: Understanding the Text
The following are model answers to the four textbook questions. Keep the main points and use your own words where suitable.
Q1. Locate the lines in the text that support the title ‘The Ailing Planet’.
Answer: The title is supported by the line, “The earth’s vital signs reveal a patient in declining health.” The author also describes the earth as facing ailing environmental conditions, disappearing forests, declining biological systems and serious pressure from population growth. These details show that the planet is unwell and needs care.
Q2. What does the notice ‘The world’s most dangerous animal’ at a cage in the zoo at Lusaka, Zambia, signify?
Answer: The cage contains a mirror, so visitors see themselves. The notice suggests that human beings are the most dangerous animals because their greed, carelessness and misuse of natural resources can damage the earth and threaten other forms of life. The author wants humans to replace domination of nature with partnership.
Q3. How are the earth’s principal biological systems being depleted?
Answer: The four systems are fisheries, forests, grasslands and croplands. Fisheries are damaged by overfishing. Forests are cut down, often for firewood. Grasslands are overused and become barren wastelands. Croplands lose their productivity. Human demands are exceeding the ability of these systems to recover.
Q4. Why does the author aver that the growth of world population is one of the strongest factors distorting the future of human society?
Answer: A rapidly growing population increases the demand for food, water, land, fuel, jobs and public services. The earth’s resources are limited, and excessive pressure reduces their ability to support people. It can deepen poverty and make it harder to provide a decent life for everyone. Therefore, the author supports development and voluntary family planning.
10. NCERT: Talking about the Text
These textbook prompts are for group discussion. The responses below are sample points, not the only acceptable views.
Q1. “Laws are never respected nor enforced in India.” Discuss.
Answer: The statement is too general if taken literally. India has many environmental laws and agencies, but enforcement can be weak because of poor monitoring, delay, lack of public awareness and pressure from powerful interests. Citizens, local bodies and government departments must work together. Laws can protect the environment only when they are followed and violations are acted upon.
Q2. “Are we to leave our successors a scorched planet of advancing deserts, impoverished landscapes and an ailing environment?” Discuss.
Answer: This question warns us about the results of careless use of natural resources. Deforestation, pollution, overuse of water and damage to soil can make life harder for future generations. We should protect forests, conserve water, reduce waste and use resources responsibly. Development must not destroy the natural systems on which life depends.
Q3. “We have not inherited this earth from our forefathers; we have borrowed it from our children.” Discuss.
Answer: The quotation means that the earth is not ours to damage for short-term gain. We hold it in trust for the next generation. We should use its resources carefully and pass on clean air, safe water, fertile soil and healthy forests. Our actions today will shape the lives of people in the future.
Q4. Discuss the problems of overpopulation that directly affect our everyday life.
Answer: Overpopulation can increase competition for schools, jobs, housing, transport, water and health services. It may lead to crowded homes, traffic, pollution, rising prices and pressure on public facilities. It can also increase demand for food, fuel and land. Better education, health care, employment and voluntary family planning can help families and communities.

13. Extra Exam Questions and Answers
Q1. What is meant by the Era of Responsibility?
Answer: It is the new phase in which people understand that they have a duty to protect the earth. It asks individuals, governments and industries to act as responsible caretakers of the planet.
Q2. Why does Palkhivala compare the earth to a living organism?
Answer: The comparison shows that the earth has connected systems and natural processes. Damage to one part can affect other parts. Human beings must respect these processes and protect the balance of nature.
Q3. What role should industries play in protecting the environment?
Answer: Industries should reduce pollution, use resources carefully, prevent waste and improve their environmental performance. The author gives the example of Edgar S. Woolard, who described himself as the Chief Environmental Officer of Du Pont.
Q4. What is the importance of Article 48A?
Answer: Article 48A of the Indian Constitution directs the State to protect and improve the environment and safeguard the forests and wildlife of the country. The author refers to it while pointing out the need for proper enforcement of environmental laws.
Q5. Explain the comparison between the earth and a life tenancy with a full repairing lease.
Answer: The comparison means that no generation owns the earth permanently. People may live on it and use its resources, but they must maintain it and pass it on in good condition. The phrase “full repairing lease” stresses the duty to repair and care for what has been entrusted to us.
Q6. Why are tropical forests important?
Answer: Tropical forests support a wide variety of living species and are described in the article as the “powerhouse of evolution”. Their destruction threatens habitats and can lead to the extinction of species.
Q7. Explain the phrase “domination to partnership”.
Answer: Domination means treating nature as something humans can control and exploit without limits. Partnership means living with nature responsibly, respecting its limits and protecting the systems that support all life.
Q8. Why should the statistics in the article be treated as historical figures?
Answer: The article was published in 1994. Its population estimates and environmental figures describe the period in which it was written. They help us understand the author's argument but should not be quoted as current measurements.
Long-answer practice
Q9. How does Nani Palkhivala build the case for protecting the earth?
Answer: Palkhivala begins with the growth of the Green Movement and the change from a mechanical to an ecological view of the world. He presents the earth as a living organism whose health is declining. He explains sustainable development and uses the mirror in the Lusaka Zoo to show that humans are responsible for much environmental damage. He then gives examples of pressure on fisheries, forests, grasslands and croplands. He discusses forest loss, weak enforcement of environmental laws and rapid population growth. Finally, he calls on people and industries to accept responsibility. His argument is that human welfare depends on a healthy planet and that resources must be protected for future generations.
Q10. “The Ailing Planet” is both a warning and a call to action. Explain.
Answer: The title warns that the earth is in poor health because of deforestation, overuse of biological systems, pollution and population pressure. These problems can reduce the earth’s ability to support life. However, the author does not present the future as hopeless. He describes the Green Movement, sustainable development and the Era of Responsibility as signs of a new attitude. Governments must enforce laws, industries must improve their environmental performance and individuals must use resources carefully. The article therefore asks readers not only to worry about the planet but also to take practical steps to protect it.
