A recent study conducted by UNICEF says over 450 million children globally live-in areas of high or extreme vulnerability. This means that one in five children across the countries don't have access to sufficient water. This could be due to various reasons including Groundwater mining, Low rainfall, Polluted water bodies, Climate change and Population explosion. The data highlights children in more than 80 countries live in areas with high or extreme water vulnerability. 37 countries including Afghanistan, Ethiopia, Nigeria and Pakistan identified as hotspot places.
