Sanjay Gupta: (on what solutions he thinks will spread access to clean water) Earlier this year, I hosted a documentary called The Survival Project: One Child at a Time for CNN. One of the special guests was actress Lucy Liu, who spent time all over the world looking at the issues of clean water and its impact on communities. I have seen how people living in underrepresented places may spend their entire day traveling to wells with a bucket in hand. The walk takes them hours and then of course, hours to walk back with heavy water in hand. It is impossible to live a healthy life, let alone make a life. I was pretty inspired to read about the TAP project, a fund-raising campaign. You can read about it more at UNICEF's website, but it will remind you of the value of tap water, and what we can do right now to improve the access to something we take for granted.
