Water Pollution

Water pollution happens when harmful substances such as sewage, chemicals, and industrial waste enter rivers, lakes, and oceans.

Soil Pollution

Soil pollution is caused by excessive use of fertilizers, pesticides, plastics, and industrial waste, reducing soil fertility.

Noise Pollution

Noise pollution is caused by loud and unpleasant sounds from vehicles, machines, loudspeakers, and industries.

Methods to Control Pollution

Pollution can be controlled by:

  • Planting more trees

  • Reducing the use of plastics

  • Using clean and renewable energy

  • Proper waste management

  • Recycling and reusing materials
