You might not believe it, but while two-thirds of the Earth is covered by water, only 3% of it actually is drinkable. This means that roughly 1 billion people are unable to find the clean drinking water they need to survive. When you add inadequate sanitation to the equation, the number of people put at risk more than doubles. This culminates in the heartbreaking stat that over 3 million people die yearly from water-related diseases.
