Creation Assistance has a post up on Water Harvesting towers in Ethiopia.  They had me until I read that the material is made from polythylene textile.  I read a couple of websites on polythylene, and they claim that it is not toxic although it is made from petroleum.  I don’t buy it.  How many times have they claimed that there are certain plastics that are safe….only to be told many years or decades later that they were, in fact, toxic?  Meanwhile, we poison ourselves and our kids…

So. although I think it’s a great idea, there has to be a natural material that can be used to collect the water…perhaps hemp fabric woven with bamboo?
