Thursday is World Water Day, an annual celebration initiated by the United Nations to raise awareness about water scarcity and how to preserve and use it safely. Even though water covers almost three-fourths of the Earth’s surface, there are many regions that are severely deprived of it.

"The theme for World Water Day 2018 is ‘Nature for Water’ – exploring nature-based solutions to the water challenges we face in the 21st century," according to the official website. "Damaged ecosystems affect the quantity and quality of water available for human consumption. Today, 2.1 billion people live without safe drinking water at home; affecting their health, education and livelihoods... Sustainable Development Goal 6 commits the world to ensuring that everyone has access to safe water by 2030, and includes targets on protecting the natural environment and reducing pollution."

This year, World Water Day turns 25 and to celebrate the occasion, here are some facts and quotes about water, courtesy of Water.org.
