Water is the core element enabling any type of life on Earth. It is essential for the development of plants and animals and remains the main resource that enables human beings to survive. Today, more than 600 million people do not have access to drinking water. In many countries, increasing desertification threatens entire populations with extinction. In fact, 84% of those without access to water survive only through agriculture. Lack of water is a direct cause of poverty and increased inequality, because without it millions of people cannot cultivate their land or raise livestock for food.
