The document discusses water usage and access around the world. It notes that in the US, most water is used for flushing toilets, while many people globally lack access to clean water. Around 750 million people do not have drinking water, and 2.5 billion lack access to toilets. On March 22nd, World Water Day is observed to raise awareness of these issues and fund efforts to provide water access. Events like walks and donations aim to help the 1.4 billion children who die from diarrhea annually due to dirty water.
