We recently highlighted how safe drinking water is in short supply. According to research published in the journal Science Advances, at least two thirds of the global population – more than four billion people – live with severe water scarcity for at least one month every year. And 500 million people around the world face water scarcity all year.
Water is a simple chemical compound containing two hydrogen atoms and one oxygen atom connected by covalent bonds. It covers 71% of Earth’s surface and is vital for all forms of life. Despite its abundance, water that is safe for drinking is globally in short supply.
