March 22, 2019, is World Water Day. Water is a basic human right. According to the United Nations, Water scarcity affects more than 40% of people (40% !) around the world, and this is projected to increase with the rise of global temperatures. Providing clean water and sanitation for all is a huge challenge.
Many research organizations note that a billion people and countless billions of animals and plants are in danger of running out of access to fresh water by natural or irrigated sources. Between overuse, climate change, and contamination, there are water crises unfolding in arid regions.
Space technologies can’t solve the problem, but it can help: European Space Agency (ESA) has published a video to celebrate World Water Day 2019 and to take a look at ways that space can help this global challenge.
