प्रश्न
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.
उत्तर
While non-biodegradable wastes cannot be decomposed and thus pollute the environment, biodegradable wastes can be converted into manure by soil microbes.
- Impacts of accumulated biodegradable waste on the environment if not disposed of properly are:
- Methane and other greenhouse gases are released as a result, which furthers global warming.
- It can cause diseases to spread because it serves as a breeding ground for microorganisms that cause illnesses.
- Impacts of accumulated non-biodegradable waste on the environment if not disposed of properly are:
- It may result in pollution of the air, water, land, and soil, which could be detrimental to both human health and the environment.
- Animals might mistake the waste for food or become entangled in it, harming wildlife.
