What is our environment?

Our environment is everything around us โ€” both natural and man-made. It includes the air, water, land, plants, and animals (the natural environment), as well as buildings, roads, and machines that people have built (the man-made environment).

Why it matters โ€” A healthy environment keeps the air clean to breathe, water safe to drink, and land fertile to grow food โ€” everything living, including us, depends on it.
10.2

Types of pollution

Air pollution

Caused by smoke from vehicles, factories, and burning waste, making air unsafe to breathe.

Water pollution

Caused by dumping waste, chemicals, and sewage into rivers, lakes, and oceans.

Land pollution

Caused by littering, dumping garbage, and using too many chemicals on soil.

Noise pollution

Caused by loud traffic, machinery, and construction that disturbs people and animals.

10.3

Effects of pollution

1Effects on health

Polluted air and water can cause breathing problems, illnesses, and make it unsafe for people and animals to drink water or breathe easily.

2Effects on nature

Pollution can harm plants and animals, damage habitats, and make soil less fertile for growing crops.

Watch out โ€” Pollution doesn't only affect the place where it happens โ€” polluted rivers carry waste downstream, and polluted air can travel far on the wind, affecting places far from the original source.
10.4

Protecting our environment

We can help protect the environment by following the 3 Rs: Reduce what we use, Reuse items instead of throwing them away, and Recycle materials like paper and plastic. Planting trees, saving water, and using less energy also help.
