March 22nd is World Water Day. To be conversant about water and issues around its uses, here are some fascinating facts and statistics compiled by UN Water.

97.5% of all water on Earth is salt water, leaving only 2.5% as fresh water. Of this nearly 70% is frozen in the icecaps of Antarctica and Greenland; most of the remainder is present as soil moisture, or lies in deep underground aquifers as groundwater not accessible to human use. Only 1% of the world’s fresh water is accessible for direct human uses – all uses – including drinking, bathing, agriculture and manufacturing.
