We turn our thoughts to thirst, and the need people have for water. There are about 1 billion people in the world right now who do not have clean water to drink. Some live in arid regions or areas experiencing drought. Others have water that is polluted by sewage and chemicals, making it unfit to drink. Some spend two or three hours out of every day walking from their homes to places where they can get drinking water to carry home to their families, and even then it may be disease-ridden and dirty.
At the same time, genuine solutions are not so simple as shipping bottles of water to be passed out to thirsty people in foreign countries. People not only need sustainable supplies of water, but also education about how to use the water and keep it clean.
