Question

Write one difference between biodegradable and non-biodegradable wastes. List two impacts of each type of the accumulated waste on environment if not disposed off properly.

Accepted Answer

Characteristics Biodegradable Waste Non-biodegradable waste

Decomposition Naturally broken down by microorganisms into harmless substances like water, carbon dioxide, and organic matter. Not easily broken down by natural processes and persist in the environment for a long time.

Two impacts of accumulated biodegradable and non-biodegradable waste on the environment when not disposed of properly:

Impacts of Accumulated Biodegradable Waste:

Air and Water Pollution: Improper disposal of biodegradable waste, such as food scraps can lead to the formation of landfills. As these materials break down, they release methane, a potent greenhouse gas, into the atmosphere. Additionally, rainwater leaching through these sites can pick up organic matter and other pollutants, resulting in the contamination of groundwater and nearby water bodies.

Spread of Diseases: Accumulated biodegradable waste can attract pests, insects, and rodents that thrive on organic materials. These pests can spread diseases to humans and animals, creating health hazards in the surrounding areas. Flies and rodents, for instance, can carry pathogens and contribute to the spread of illnesses.

Impacts of Accumulated Non-Biodegradable Waste:

Environmental Degradation: Non-biodegradable waste, such as plastic bags, bottles, and packaging materials, can persist in the environment for decades or even centuries. The accumulation of such waste in landfills, oceans, and natural habitats contributes to pollution, disrupts ecosystems, etc.

Microplastic Contamination: Non-biodegradable plastics gradually break down into smaller fragments known as microplastics. These tiny particles can enter the food chain when consumed by aquatic organisms, and eventually, even humans. They can cause health hazard.
