Natures Habit — we live in 2060, ecosphere systems on the verge of collapse. A group of scientists and environmentalists named «Hourglass» gathered from around the world to save the remains. They found that experiments in small terrariums could be effective and would eventually shed light on correcting real ecosphere systems. You are playing for a synthetic drop of water, which is designed to help these scientists by completing the habit of nature, according to which all living things depend on water.
