- Representations of the Earth’s water cycle used in textbooks throughout the world need to be updated, say scientists who have drawn up a new set of diagrams to include effects of human interference.
- Leaving humans out of the picture contributes to a basic lack of awareness of how humans relate to water on Earth and a false sense of security about future availability of this essential and scarce resource, according to the study published in the journal Nature Geoscience.
- The team from the University of Birmingham in the UK, Brigham Young University and Michigan State University in the US has drawn up a new set of diagrams to promote better understanding of how our water cycle works in the 21st century.
- These new diagrams show human interference in nearly all parts of the cycle.
