I've heard that a lot of people in the world don't have access to clean drinking water. Is that true?

Yes, it is true that many people in the world do not have access to clean drinking water. According to the World Health Organization (WHO), 2.4 billion people lack access to safe drinking water and almost half of the world's population does not have adequate sanitation facilities. This means that these people are at risk for contracting waterborne diseases such as cholera, typhoid, hepatitis A and E, and other illnesses.
