We are quickly heading toward a massive water crisis that will affect the entire world. According to the World Health Organization, one in three people already does not have access to clean drinking water as of today.

It is estimated that 2 billion people have to use a drinking source that is contaminated with feces. Unfortunately, researchers predict that by 2025 half the world’s population will live in water-stressed areas.

On top of the current water scarcity, scientists expect that more water sources will be contaminated by undrinkable saltwater as sea levels continue to rise due to climate change.
