“We are all here for one reason: because more than half the world’s population doesn’t have the safe sanitation they need to lead healthy and productive lives,” Gates said in a speech on Tuesday in Beijing.
Gates tweeted a video Monday that described his and his foundation’s mission to improve sanitation for countries that do not have or cannot afford to build the sewer infrastructure to remove waste.
To drive home the importance of safe sanitation, Gates brought a jar of feces with him during his keynote in Beijing.
“You might guess what’s in this beaker—and you’d be right. Human feces. This small amount of feces could contain as many as 200 trillion rotavirus cells, 20 billion Shigella bacteria, and 100,000 parasitic worm eggs,” the Microsoft co-founder said.
He kept the jar on the podium for nearly 10 minutes before removing it, the
Associated Press reported.
Poor sanitation kills nearly 500,000 children under the age of five annually and costs an estimated $223 billion a year in the form of higher health costs and lost productivity and wages, Reuters reported, citing the information from the
Bill and Melinda Gates Foundation.
The untreated sewage can also negatively impact the surrounding environment.
“Some of the untreated human waste is in unlined pit latrines that contaminates groundwater around people’s homes,” Gates said in his speech. “Some is collected manually, or by trucks, and is dumped into nearby fields or bodies of water. And some is collected in sewers but never gets treated. The point is that we are far from the goal the world set in 2015 of everyone using a safely-managed toilet.”
The aim of the expo is to “launch a new category of innovative, decentralized sanitation solutions that will benefit millions of people worldwide,” Gates said.
Several of these “reinvented toilets” are currently being tested in Durban, South Africa.
