Answer
Three ways by which landfills cause harm to our environment are:
- Soil and Water Pollution — Most of the waste ending at a landfill site contains toxins. These toxins over a while seep into the ground and contaminate groundwater in the form of leachate and contaminate soil.
- Health Hazards and Disease Spread — They are potential breeding grounds for bacteria, mosquitoes, rats and other scavengers spreading diseases.
- Harm to Biodiversity — Landfills can destroy natural habitats and threaten local flora and fauna, reducing biodiversity in the area.
