Correct option is B
Animal agriculture consumes large amounts of water (e.g., beef production requires over 15,000 liters of water per kg).
Water conservation through dietary change is a sustainable and long-term strategy.
- Increase food waste: Leads to wastage of all resources, including water, used in producing the wasted food.
- Decontamination process during filtration: This purifies water, It helps in quality improvement.
Boil water: Useful for disinfection, but involves water loss via evaporation and energy consumption.
Important Point: Adopting sustainable dietary practices is an efficient way to mitigate water scarcity.
