Here in North America, clean water is something we most certainly take for granted. We flush it down the toilet and the sink, we throw it out if it is not perfectly fresh. We're afraid of out perfectly clean tap water so we invest in expensive filters or buy our water from the store. And yet so many people out there would do anything for that tap water.

Here's a story from Dr. Gupta, CNN's medical correspondent, about a village in China that gets its water supply from the Hengshui River, which happens to be the river that receives heavy metal and mining deposits. On a scale of 1 to 5, 5 being the most toxic--too toxic to safely touch, let alone ingest--the Hengshui rates a staggering 5. Full of known carcinogens like arsenic, lead, zinc and cadmium, the water is slowly killing the people who rely on it, and they have no choice but depend on this water source -- there are no others.

I can't imagine living in a world where the price you pay for water is your life, where you can't rely on anyone to step in and make sure you have a clean water supply. It's truly heartbreaking.
