In La Paz, Bolivia, children are learning how to wash their hands thoroughly, as you can see in this video from the field. On March 22, we celebrated World Water Day, which highlights water’s important role in health, sanitation, agriculture, industry and education. When clean water is hard or impossible to access — as it is for 748 million people worldwide, according to the United Nations — the most vulnerable among us, including infants and children, tend to get sick and lose time at school, become malnourished and even die from preventable diseases. Making water available in communities and showing families how to protect themselves from diseases are two of ChildFund’s most important goals. Learn more about how you can help.
