Nani Palkhivala The Ailing Planet Long Question Answers
Long answers should combine facts, examples, and the author’s message. Students should avoid writing only one-line definitions.
These The Ailing Planet long question answers cover common 5-mark areas.
Q37. Explain the role of the Green Movement in changing human thinking.
The Green Movement changed human thinking by creating worldwide ecological awareness.
Before this shift, people often saw nature as a resource to control. The movement helped people see the earth as a living organism with its own needs.
Palkhivala compares this change with the Copernican revolution. Both changed how humans understood their place in the universe.
The Green Movement also promoted sustainable development. It made people think about future generations, not only present comfort.
Q38. How does Palkhivala explain the declining health of the planet?
Palkhivala explains the planet’s decline through damaged biological systems and rising population.
He says fisheries, forests, grasslands, and croplands support the global economy. Human pressure has pushed these systems towards unsustainable levels.
Forests are disappearing at alarming rates. Grasslands become barren, croplands deteriorate, and fisheries collapse.
Population growth worsens the problem. It increases poverty, demand for fuel, pressure on land, and strain on natural resources.
Q39. Why does the author say population growth distorts the future of human society?
Population growth distorts the future because it increases poverty and resource pressure.
The world took more than a million years to reach the first billion. The twentieth century added billions more.
More people need more food, fuel, housing, education, and jobs. Poor families often have more children, which keeps poverty alive.
The author supports voluntary family planning. He says the real choice is between population control and continued poverty.
Q40. Explain the idea that humans are trustees of the planet.
Humans are trustees because they must protect the earth for future generations.
A trustee uses property responsibly and preserves it for others. The author applies this idea to the planet.
Margaret Thatcher’s statement supports this idea. She said no generation has a freehold on the earth.
Lester Brown expresses the same idea differently. He says humans have borrowed the earth from their children.
Q41. How does The Ailing Planet balance warning with hope?
The essay warns about environmental collapse but also offers responsibility as hope.
It shows serious threats like forest loss, population growth, species extinction, and resource depletion. These facts make the planet appear like a patient in declining health.
Yet the essay does not end in despair. It says the environmental problem is a passport for the future.
The hope lies in sustainable development, law enforcement, industry responsibility, and ecological awareness.
