Eco-friendly Practice Identification
The question asks to identify an eco-friendly practice from the given options. An eco-friendly practice is one that is sustainable and minimizes harm to the environment.
Analysis of Options
- Option 1: Disposal of biodegradable wastes in ponds - This can lead to water pollution and harm aquatic life due to nutrient overload. It is not considered eco-friendly.
- Option 2: Use of chemical fertilizers to increase crop productivity - While increasing productivity, chemical fertilizers can degrade soil health, pollute water sources through runoff, and are unsustainable.
- Option 3: Disposing dry leaves in pits under soil - This practice allows leaves to decompose naturally, enriching the soil with nutrients. This process, similar to composting, is beneficial for soil health and is an eco-friendly method of waste management.
- Option 4: Disposing waste plastics by dumping in pits under soil - Plastics are non-biodegradable and persist in the environment for long periods, causing soil and groundwater pollution. This is harmful to the ecosystem.
Conclusion on Eco-friendly Practice
Based on the analysis, disposing of dry leaves in pits under soil is the most environmentally sound practice among the choices. It promotes natural decomposition and soil improvement, aligning with sustainable environmental principles.
