To raise awareness of this challenge, I've shared a stage with a jar of human feces. “...a container of human feces.” I've taken a giant wiff of pit latrine odor. “Terrible.” I drank water made from fecal sludge. And I convinced some friends to drink it too. “Thank you, buddy.” All of these stunts got some laughs, but my goal was to draw attention to a serious problem: poor sanitation. More than 500,000 people die every year from sanitation-related diseases. But this problem can be solved. In the decade since the launch of the Reinvent the Toilet Challenge the world has responded with the power of innovation. Creative minds from across the globe developed hundreds of new and exciting ideas for how to design toilets and process human waste with little or no need for water and electricity. Toilets that convert human waste into valuable resources, including fertilizer, biochar and electricity. And a new system to process fecal sludge from pit latrines, septic tanks and sewers that turns human waste from entire communities into electricity. What's exciting is that over the last decade, many of these promising concepts have gotten more efficient and affordable. Challenges remain to get these innovations to market so that they can transform the lives of the billions of people who need them. But I'm optimistic about the progress we can make in the next 10 years and beyond. What inspires me most is the dedication and passion of the people who've come together to answer this call. Governments, researchers, businesses, philanthropies and communities are working together to embrace smart approaches to safe sanitation, especially in slums and other underserved communities. Together they are leading a sanitation revolution. It can't happen fast enough.
