Globally, about 6,000 people a day die from water-borne disease. These are preventable deaths but, in many places it is too expensive to provide clean water for everyone and as a result people contract water-borne diseases. A fancy new drinking straw can stop 99.99% of parasites and bacteria from drinking water.
It’s called the Lifestraw and is currently being tested in the field. It is not as small as your average straw, but it’s small enough to wear around your neck. The manufacturing costs are low too – only $3 per unit. 70,000 units were handed out to earthquake victims in Kashmir last year. More testing is needed, but this is off to a very promising start!
