What is the environment?
The word ” environment ” means everything around us.
We are surrounded by many living and non-living things every day. These things help us live comfortably and safely.
Our environment includes:
- Air
- Water
- Soil
- Trees
- Plants
- Animals
- Birds
- Mountains
- Rivers
- Sunlight
- Human beings
- Houses
- Roads
- Schools
In simple words:
The environment is everything that surrounds us and affects our lives.
For example:
When you breathe fresh air, drink water, sit under a tree, or play in a park, you are using different parts of the environment.
Understanding Environment with a Simple Example
Imagine you are sitting in a garden.
Around you, there are:
- Green grass
- Trees
- Flowers
- Butterflies
- Birds
- Sunlight
- Fresh air
- Soil
All these things together make up your environment.
Without these things, life would become difficult.
That is why the environment is very important for every living being.
Types of Environment
According to Class 3 Our Environment Chapter Notes, there are two main types of environment.
1. Natural Environment
The natural environment includes everything created by nature.
Examples:
- Mountains
- Rivers
- Oceans
- Forests
- Trees
- Animals
- Birds
- Air
- Water
- Sunlight
Nature provides everything needed for life.
Examples of the Natural Environment
- The Himalayan Mountains
- Forests full of animals
- Rivers flowing with water
- Green trees and plants
Humans do not make these.
2. Man-Made Environment
The man-made environment includes things created by people.
Examples:
- Houses
- Schools
- Roads
- Bridges
- Cars
- Hospitals
- Parks
- Factories
Humans create these things to make life easier.
Examples of Man-Made Environment
- Your school building
- A playground
- A shopping mall
- A bridge over a river
These things are made by people, not by nature.
Components of the Environment
The environment has two important components.
1. Biotic Components (Living Things)
The word “Biotic” means living.
These are things that can:
- Grow
- Breathe
- Reproduce
- Move
Examples:
- Humans
- Plants
- Trees
- Animals
- Birds
- Insects
- Fish
Examples Around Us
A dog in your house, a sparrow on a tree, and a mango plant in your garden are all biotic components.
2. Abiotic Components (Non-Living Things)
The word “Abiotic” means non-living.
These things do not grow or reproduce.
Examples:
- Air
- Water
- Soil
- Rocks
- Sunlight
- Temperature
These non-living things help living things survive.
Without water and air, plants and animals cannot live.
Relationship Between Living and Non-Living Things
Living and non-living things depend on each other.
For example:
Plants Need:
- Water
- Soil
- Sunlight
- Air
Animals Need:
- Water
- Food
- Air
Humans Need:
- Food
- Water
- Air
- Shelter
This shows that every part of the environment is connected.
Importance of the Environment
According to Class 3 Our Environment Chapter Notes, the environment is essential for life.
Let us understand why.
It Gives Us Air
We need oxygen to breathe.
Trees and plants help provide fresh oxygen.
Without air, humans and animals cannot survive.
It Gives Us Water
Water is needed for:
- Drinking
- Cooking
- Cleaning
- Farming
Every living thing needs water.
It Gives Us Food
Many foods come from nature.
Examples:
- Fruits
- Vegetables
- Grains
- Milk
- Honey
Farmers grow crops using soil, water, and sunlight.
It Gives Us Shelter
Wood, soil, stones, and other natural resources help us build homes.
It Maintains Balance in Nature
Plants, animals, birds, and humans depend on each other.
This natural balance keeps Earth healthy.
Natural Resources
Natural resources are gifts from nature.
They help us meet our daily needs.
Examples include:
- Air
- Water
- Soil
- Sunlight
- Minerals
- Forests
We should use natural resources carefully because some resources are limited.
Plants and Environment
Plants are one of the most important parts of our environment.
Plants help us in many ways:
- Give oxygen
- Provide food
- Prevent soil erosion
- Give medicines
- Provide shade
- Keep the air clean
Why Trees Are Important
Trees:
- Absorb carbon dioxide
- Release oxygen
- Reduce pollution
- Provide homes for birds
That is why we should plant more trees.
Animals and Environment
Animals are also an important part of nature.
Different animals help the environment in different ways.
Examples:
- Bees help in pollination.
- Earthworms make soil fertile.
- Birds spread seeds.
- Cows provide milk.
Every animal has an important role in nature.
What is Pollution?
Pollution means making the environment dirty and unsafe.
When harmful substances enter air, water, or land, pollution occurs.
Pollution affects:
- Humans
- Animals
- Birds
- Plants
It can cause diseases and damage nature.
Types of Pollution
1. Air Pollution

- Factory smoke
- Burning garbage
- Firecrackers
Effects of Air Pollution

- Cough and asthma
- Dirty air
- Global warming
2. Water Pollution
Water pollution occurs when water becomes dirty.
Causes of Water Pollution
- Plastic waste
- Factory waste
- Sewage water
- Garbage thrown into rivers

Global Warming (Easy Explanation)
When pollution increases, Earth’s temperature slowly rises.
This is called Global Warming.
Global warming can cause:
- Hotter summers
- Melting glaciers
- Less rainfall in some places
- Climate changes
Planting trees can help reduce global warming.
For additional learning, students can explore environmental education resources from the UNEP (United Nations Environment Programme) and National Geographic Kids.
