Water covers 70% of our planet, and it is easy to think that it will always be plentiful.
However, freshwater—the stuff we drink, bathe in, irrigate our farm fields with—is incredibly rare.
Only 3% of the world’s water is fresh water, and two-thirds of that is tucked away in frozen glaciers or otherwise unavailable for our use.
As a result, some 1.1 billion people worldwide lack access to water, and a total of 2.7 billion find water scarce
for at least one month of the year.
Inadequate sanitation is also a problem for 2.4 billion people—they are exposed to diseases,
such as cholera and typhoid fever, and other water-borne illnesses.
Two million people, mostly children, die each year from diarrheal diseases alone.
