The blue planet and our address
From space, astronauts see no lines between countries, only land, water and clouds. Our Earth looks like one home.
From space the Earth looks blue because water covers most of it, and no borders are visible. Astronauts like Rakesh Sharma and Shubhanshu Shukla have seen it that way. Every person has an address that goes from house to street, town, district, state, country and finally the planet Earth. DIGIPIN is a 10-character digital address code. A globe helps us find India and see that the oceans are connected.
In the figure: Our address ends with planet Earth.
Key point 1: Seeing Earth from space
- Easy : Earth looks blue and has no visible borders from space.
- Medium : Only broad shapes of land and sea can be seen, not cities or villages.
- Exam-type : Astronauts felt Earth is one home for all.
Key point 2: Addresses
- Easy : A full address goes from house to planet.
- Medium : DIGIPIN gives small places a 10-character digital code.
- Exam-type : A globe shows that all oceans are connected.
Earth is the only planet we know that has life.

Nature has no boundaries: travelling birds
Every winter, pink-and-black birds arrive in large flocks in India from faraway lands.
Air, water, clouds, seeds and animals cross boundaries freely. The rosy starling migrates every winter from places like Russia and Mongolia to India, enjoys the warm weather and eats locusts and grasshoppers, helping farmers by eating pests. Such journeys show how nature is connected across the world. Wind, ocean currents and warm weather help birds travel.
In the figure: Birds travel across countries without needing passports.
Key point 1: Migration
- Easy : Migratory birds travel to another region for a season.
- Medium : The rosy starling comes to India in winter.
- Exam-type : Wind and weather help them on the way.
Key point 2: Helpful travellers
- Easy : They eat locusts and grasshoppers that harm crops.
- Medium : Farmers benefit from the birds' visit.
- Exam-type : Nature has no boundaries, so countries must care for birds together.
Animals and seeds move without borders; that is why nature care is shared.
Thinking birds belong to one country only.
Migrate = move for a season. Memory clue: "Migrate = My Great Trip".

Things that travelled across the world
The chilli in your curry, the marigold garland and even the cow giving milk may have come from far away.
Plants, foods, animals and ideas travel through trade and travel. Chilli came from South America to India with Portuguese travellers 400–500 years ago; before it, people used black pepper. Sugar and jaggery, rice, mangoes and bananas travelled from India; so did yoga. The marigold came from Mexico. Indian cow breeds like Gir, Kankrej and Ongole went to Brazil and give much of its milk.
In the figure: Shared things blend cultures across the world.

One Earth, one family
Trees, rivers, animals, air and people all share one home. How should we treat our shared house?
An old Indian saying, Vasudhaiva Kutumbakam, means "the world is one family". Earth is the only planet we know that has life, and everyone and everything on it depends on each other. When we see the world as one family we live with respect, care and love. Earth needs our care; protecting it is caring for each other and for the future. The Environment Ministry's logo reminds us that humans and nature must live in balance.
In the figure: We are one family on one Earth.
