So I found this great article in the New York Times this morning about the problems with creating access to clean water in the poorer (and drier) parts of the world. Most of the water pumps that groups and companies install fall into disrepair because the people do not know or cannot afford to maintain them. These water supplies are also easily contaminated. So how do we solve the problem? Apparently, by creating great filters.
The is already a personal filter that allows hikers to drink out of any pool. This type of filter, according to the opinion piece, can be implemented on a greater scale and work for families to clean water for up to three years. According to the article, the companies that make them can give them for free to families who need them because the filters replace the boiling of water (burning wood to make the fire is essentially a carbon emission) and the companies can profit from the reduction of pollutants (through carbon credits) and still make the filters free to the people that need them. It's a pretty sweet deal.
