Fresh water is the most important resource for human life on earth. People can survive far longer without food than without water, and virtually all of our food sources require fresh water to grow or create.
A massive freshwater sea has been discovered off the North East coast of the US, beneath the Atlantic Ocean no less.
Scientists have now quantified the global decline of big freshwater animals: From 1970 to 2012, global populations of freshwater megafauna declined by 88% - twice the loss of vertebrate populations on land or in the ocean. Large fish species are particularly affected.
In 2018, Cape Town, South Africa's second most populous city, came very close to running out of water as the multi-year "Day Zero" drought depleted its reservoirs.
