In the future, human beings may develop advanced technology to make fresh water from salty water through a process called desalination. Desalination involves removing the salt and other impurities from seawater or brackish water to produce clean, drinkable water. This technology could help alleviate water scarcity issues in regions where fresh water sources are limited. By harnessing the power of innovation and science, we can ensure a sustainable future for generations to come.
