It involves adopting practices like rainwater harvesting, efficient irrigation techniques, and reducing water wastage. By conserving water, we can ensure its availability for future generations, minimize the strain on water sources, and protect ecosystems that depend on water.
5. What are the potential solutions to address water scarcity?
Ans. Several potential solutions can help address water scarcity. These include implementing efficient water management practices, investing in water infrastructure, promoting water recycling and desalination technologies, and raising awareness about the importance of water conservation.
