Q1.
What does it mean when we say ‘nature has no boundaries’?
Answer

It means that the lines people have drawn between countries exist only on maps and on paper. Nature does not know about them and does not stop at them. Air, clouds, rain, rivers, seeds, birds, fish and butterflies all move freely across the world.

Look at what actually crosses:

What crossesAn example you can check
Air and windThe monsoon wind that brings our rain forms over the ocean, far from India
Clouds and rainA cloud made over the Bay of Bengal drops its rain on Assam, hundreds of kilometres away
RiversRivers begin in one land, pass through others and reach the sea in yet another
BirdsThe rosy starling flies from Russia and Mongolia to India every winter
Fish and sea animalsAll the oceans are joined, so a turtle can swim from one country's coast to another's
Seeds and plantsChilli from South America and marigold from Mexico now grow all over India
Dust and smokeDust blown from a far-off desert settles on our cities

And the sentence has a second half, which is the important one:

  1. Because nature is shared, the good is shared — rain, birds, seeds, fresh air, new foods.
  2. Because nature is shared, the harm is shared too. Smoke let into the air in one place does not stay there. Rubbish thrown into a river travels down it and out into the sea.
  3. So looking after air, water and living things cannot be one country's job. It has to be everybody's job.
Why the astronaut's words at the start of the chapter matter: Group Captain Shubhanshu Shukla said that from space the Earth looked completely one — no border was visible from outside. He was not making a wish; he was describing what he could see. The borders are real for passports and post offices. They are not real for the air you are breathing right now, which was over some other country a week ago.
Try this in class: Ask everyone to hold their breath for five seconds, then breathe out. Say: that air is now leaving the room, going out of the window, over the town and away. Nobody can call it back and nobody owns it. That is what ‘nature has no boundaries’ means, in one breath.
