SSC Selection Post 2022 PYQ — Question 33

The correct answer is option 1 i.e. non-biodegradable wastes. 

DDT and plastic are examples of non-biodegradable wastes. These substances do not decompose naturally through the action of microorganisms and can remain in the environment for hundreds of years. DDT is a synthetic pesticide, while plastic is a man-made polymer, both of which pose serious threats to soil, water, and living organisms. Their accumulation leads to environmental pollution, harming ecosystems and public health. Proper waste management and reduced usage are essential to minimise their long-term environmental impact.
