March 22 is World Water Day. Growing up, like many others, I did not appreciate how lucky I was to have clean, safe water. We need it to drink and become sick if we do not have it. We need it for agriculture and would become hungry without it. We need it for washing, bathing, and clean health care facilities. Likewise we need sanitation and hygiene to protect food, water, and health. One billion people around the world still lack clean drinking water and 2.6 billion lack access to basic sanitation. It doesn’t have to be this way. World Water Day is an opportunity to ask what we can do in the year ahead to address the world's water crisis.
