Sponsor a Lifestraw: Treehugger points out you can chip in to put a family version of the Lifestraw in more homes that need them. Lifestraw is a really slick, inexpensive (at least for rich Westerners) device that filters almost any water into drinkable. The family version turns it into a drinking source suitable for a home. The Lifestraw is one of many objects and tools designed for improving the quality of life in impoverished parts of the world and part of the exhibition Design for the other 90%, coming to the Minneapolis Sculpture Garden this summer. I don’t think the Family version is part of the show, so it is interesting to note it’s development.
