Which of the following is an eco-friendly practice?

Correct option is C

The correct answer is: (C) Disposing dry leaves in pits under soil

• Dry leaves are biodegradable and will naturally decompose over time, enriching the soil with organic matter.
• This process helps improve soil quality, promotes healthy plant growth, and reduces waste, making it a sustainable and environmentally friendly practice.

• Disposal of biodegradable wastes in ponds: While biodegradable wastes decompose naturally, disposing of them in ponds can lead to water pollution, affecting aquatic life and disrupting ecosystems.

• Use of chemical fertilizers to increase crop productivity: Chemical fertilizers can harm the environment in the long run by causing soil degradation, water pollution, and loss of biodiversity. They are not considered eco-friendly practices.

•  Disposing waste plastics by dumping in pits under soil: Plastics are non-biodegradable, and dumping them in the soil can lead to long-term environmental damage, causing soil contamination and harming plant and animal life.

Therefore, disposing dry leaves in pits under soil is the only eco-friendly practice among the given options.
