(New York Times)  Clean water is quotidian for Americans, but for much of the globe, it is a constant struggle.  Many aid groups and nonprofits make implementing clean water facilities their mission, but it is no easy venture.  Pipes break or are looted; villages do not have the money or expertise for repairs, and well-intentioned projects become dearth.  Fortunately, the issue has been recently remedied by making clean water efforts a for-profit business as opposed to its historically nonprofit status.  For-profit companies are starting to work on clean water in poorer countries and are charging no money for their efforts, instead opting for payment via global carbon credit markets.  Because of the 2007 Kyoto Protocol to reduce greenhouse gases that contribute to climate change, large companies can agree to do something “green” to even out their customary pollutions.  Vestergaard Frandsen’s LifeStraw is a water filtering system that allows people to drink clean water without boiling it.  The company is planning on distributing LifeStraws to 4 million families in Kenya free of charge.  The company is expecting approval from the carbon credit markets in February, meaning that it will earn credits for preventing greenhouse gas emissions that large, polluting companies will then purchase, creating a sustainable business at no cost to users.
