Infinite Water Inc. and Infinite Complex looks at the facts first: water is the most vital substance on our planet. Life cannot exist without it and is also central to a range of human activities. Water availability is critical for human health, environmental resilience, economic development, and food and energy security. Despite this, in many parts of the world the demand for water is greater than the available supply. Water scarcity is one of the greatest challenges facing humanity this century. About 4 billion people reside and about half the world’s irrigated agriculture is in regions that experience water scarcity.
