“Thousands have lived without love, not one without water.” Despite the fact that we all know how important water is for life, we continue to waste it. Approximately 80% of the world's wastewater is thrown back into the environment, mainly untreated, contaminating rivers, lakes, and seas. Our health is being jeopardised by the pervasive problem of water contamination. Each year, unsafe water kills more people than all other types of violence combined. Meanwhile, our supplies of potable water are limited: We have access to less than 1% of the world's freshwater supply. If nothing is done, the problems will only become worse by 2050, when global freshwater demand is anticipated to be one-third more than it is currently. Water is very susceptible to contamination. Water, sometimes known as a "universal solvent," can dissolve more compounds than any other liquid on the planet. It's why we have Kool-Aid and gorgeous blue waterfalls. It's also the reason why water is so readily contaminated. Toxic chemicals from farms, cities, and factories easily dissolve and combine with it, polluting the water.
