I'd say corruption and failing infrastructure is a bigger threat to water supplies, but far be it for me to contradict the Current Narrative of 'settled science'.

Vital and appreciated as that water is, it will be even more precious to those who will follow you.

By the end of this century, billions are likely to be gripped by water stress and the stuff of life could be an unseen driver of conflict.

So say hydrologists who forecast that on present trends, freshwater faces a double crunch -- from a population explosion, which will drive up demand for food and energy, and the impact of climate change.

"Approximately 80 percent of the world's population already suffers serious threats to its water security, as measured by indicators including water availability, water demand and pollution," the Nobel-winning Intergovernmental Panel on Climate Change (IPCC) warned in a landmark report in March.

"Climate change can alter the availability of water and therefore threaten water security."
