Yesterday was World Water Day, launched by the UN in 1993 to raise awareness about the importance of water both environmentally and for humanity as a whole.
I think our strictly terrestrial species is ill-equipped to truly grasp the significance of water, from its role in generating most of our oxygen, to the fact that most living things that have ever lived have been aquatic or amphibious.
As a middle class person in a developed part of the world, it is also east to take for granted just how elusive access to clean water is; for most of human history, most humans died or were sickened (sometimes permanently) by diseases related to dirty water.
While we’ve made tremendous progress over the past century alone, well over a million humans still die annually from water-borne diseases (many of them children), and nearly one out of four people lack the access to clean water that most us take as a given. The effects of climate change and overexploitation risks depleting an already strained water supply—making World Water Day’s mission of awareness all the more invaluable.
Below is a big data dump concerning all things water, including the progress we’ve made in expanding clean water access, and the challenges that remain in continuing this development while doing so sustainably.
