Water is the most important resource on Earth. We drink it, wash with it, clean with it, and even study it. Without water, nothing could exist. Scientists who study water are called hydrologists. They make sure our water is clean and safe, design systems to move and collect water, and know where to find fresh sources of water. For more information on water, read Inside the Water Cycle, another book in the Mission: Science series.
