There are few experiences that are as refreshing as dipping into a cool swimming pool on a sweltering summer day. As climate change continues and summer temperatures soar, taking refuge in cool water is one way to beat the heat (and keep sanity intact). Unfortunately, most swimming pools are full of chemicals which are harmful to human skin/eyes and toxic to surrounding soil and plants. A natural swimming pool is one that is designed to harness the processes of nature to produce clean, clear water. These types of pools have been available in Europe for a while, but are only starting to catch on in North America. Fortunately, as more people become aware of the importance of environmental stewardship, these natural pools are starting to grow in popularity.
