Fun Facts

  • Animals and plants that live in polluted water may die, and we can not use it for drinking or bathing.
  • Pollution on the land is unhealthy and can make people, animals, and plants sick.
  • Pollution in the air causes smog that can be too dirty to breathe.

Why Do We Need To Know About Pollution

Studying pollution helps you see how it harms our planet. It is important to control pollution in jobs like farming and making cars. This helps in keeping the environment safe by handling chemicals the right way.

Knowing about pollution also helps in saving animals, making new green technologies, helping communities, recycling, and planning cities better. It leads to creating products that are good for the earth and teaches us how to use our resources wisely. Understanding pollution is important for work and everyday life.

Frequently Asked Questions

Why should we recycle?
To keep land, water and air clean and to have enough resources so other people can enjoy them too.
What happens to items that are not recycled?
They end up in the trash. Then a garbage truck will move it to a landfill. At a landfill trash is buried and it can also be burned which leads to air pollution.
How is water affected by pollution?
Water can get dirty. Then we cannot use it for drinking, bathing and cooking. Animals and plants that live in the water may die.
