POLLUTION Land Pollution Rubbish is dumped in landfills. Landfills become breeding ground for pests. Pests can spread diseases to us. Littering or dumping rubbish makes environment look dirty and ugly. Water Pollution Soil erosion causes water pollution. Dumping rubbish into rivers and lakes causes water pollution. Releasing waste such as sewage water into rivers and lakes causes water pollution. Oil spills from ships and oil rigs cause water pollution. Air Pollution Harmful gases released into the air makes the air unhealthy. Gases released from cars, trucks and buses. Gases released from power stations and factories. Smoke from burning rubbish. CONSERVING ENVIRONMENT Protecting environment from harm and keeping it healthy. We need to use natural resources wisely and not waste them. Reducing Land Pollution Dispose rubbish properly. Do not litter. Participate in cleaning campaign. Reducing Water Pollution Do not throw rubbish in the river. Clean sewage water at a treatment plant. Do not cut or burn trees to avoid soil erosion making the water muddy. Reducing Air Pollution Walk or ride bicycle instead of using car.
