Vast freshwater reserves found in seabed

The video explains how aquifers formed thousands of years ago and were protected from saltwater intrusion by layers of sediment and clay. Researchers discovered significant groundwater reserves, including 3.1 cubic kilometers off the coast of Gippsland, Australia, and half a million cubic kilometers worldwide. These reserves can be accessed by drilling from sea platforms, though the process is costly. The low-salt groundwater can be converted to drinking water, potentially supplying many coastal cities globally.
