What to Focus On

  • Pollution is the presence of harmful substances in the environment.
  • Substances that cause pollution are called pollutants.
  • Pollution affects air, water, land, and sound around us.

  • Air pollution: harmful gases and smoke in the air.
  • Water pollution: dirty and harmful substances in water bodies.
  • Noise pollution: very loud and unwanted sounds.

  • Main pollutants: smoke, gases, dust, and chemicals.
  • Causes: vehicles, factories, burning fuels, firecrackers.
  • Effects: breathing problems, lung diseases, global warming, acid rain.

Common Mistakes to Avoid

Only factories and vehicles cause pollution. Small actions like bursting crackers or burning leaves don’t harm the environment.

Polluted water looks dirty, so if water looks clean, it is safe to drink.

Noise pollution is just about loud sounds. It doesn’t affect health like air or water pollution.
