The correct option is D Planting trees near water bodies
Plastic is tough to break down. It is a non-biodegradable product and hence very hard to dispose of safely. Instead, the use of glass bottles is much safer for the environment. Planting trees near water bodies would help reduce soil erosion which carries pollutants into water bodies. Other methods of preventing water pollution include-
1. Avoiding littering at public places.
2. Using water efficiently while bathing, brushing, and washing.
3. Volunteering to help clean the beaches, rivers, and our locality.
