Water Follies is one of the first books I have read about the true impacts that the human population and its' many uses for water has had upon the Earth. My first degree was in Environmental Health, so I have a soft spot for water quality as well as for the sake of the Earth, for our future generations. If you hope to gain knowledge about the uses and misuses of groundwater and surface water, and the economic/legal and environmental turmoil that ensues, this is very interesting. I believe the book does not cover the environmental aspects coming to play more currently, with runoff of agricultural products, as well as the severe weather patterns occurring. Robert Glennon focuses on decreases of aquaculture and aquatic ecosystems - being that water stops flowing readily, but does not address the previously stated agricultural runoff that produces algae blooms that smother the aquatic ecosystems.
I would love to see an updated case study on many of these situations, to see how population growth and water use regulations have affected "scarcity". Worldwide water shortages are predicted to occur as soon as 2040 in terms of some research studies, so I hope that we begin to recognize the true cost of water before it is too late. I really enjoyed the reality and perspectives this book brought to the surface, per say.
