This lesson will brief you about population, examples to understand what population is and also how we can encourage wildlife by making miniature habitats.


What is Population?

The number of people in a given place is called population.

  • Number of people in the classroom.
  • Number of people at home.
  • Number of people in a village.
  • Number of people in a city.
  • Number of people in a country.
  • Number of people in the world.


In the early days there were a few people and they had so much space to live on Earth. Therefore the environments were not changed so much.


Nowadays people live and travel all over the world. Now the population or the number of people of the world is about 6 billion people. Rapid (fast) population growth uses up our natural resources and harms the environment and the environment is changed very quickly.



  • Massive areas of land are cleared to grow food and to build new homes, shops factories and roads.
  • People dig mines (pit) and quarries to get building stone, mineral and fuels. 
  • People harm the environment with noise and litter.




A habitat is a place where an animal normally lives. Forests, deserts, and wetlands are kinds of habitats.


How can you make your school ground more interesting by encouraging wildlife?


  • If your school does not have any space for a garden, you could plant flowers in tubs or inside old car or lorry tyres filled with soil or compost.
  • You could make nest boxes for birds and squirrels.
  • You could make a bird table where the birds and squirrels can feed.
  • You could grow plants with flowers that butterflies and bees like to feed on.
  • You could make a small pond which attracts frogs, toads and other animals that like water.
