I know this post does not pertain to Dominica, but I just had to share the story. Lifestraw, the portable drinking filtration system, walk off with the top honor in the fifth Saatchi and Saatchi Award for World Changing Ideas last Thursday. Worn around the neck and used like a regular straw, Lifestaw claims to filter 99.9999 percent of bacteria and 98.7 percent of viruses using a halogen-based resin.

Saatchi’s worldwide creative director Bob Isherwood had nothing but high praise for the company.

“I think it’s an amazing idea, a world-changing idea,” he said. “You have such a huge proportion of the world’s population that can’t drink safe water; 6,000 children a day dying from polluted water. To have a straw that you wear around your neck that you can put in contaminated water and turn it immediately into totally safe water is incredible; it is world-changing.”

My Thread on the Lifestraw

OK the straws filters out 99.9999 percent of bacteria and 98.7 percent of viruses, but my question is – how many bacterial cells do you need for an infection? I believe the technology is somewhat stupid and it’s just blinding people with big numbers and ignoring the real problem at hand. Let’s hear your opinion in the comments.
