This, the second article in the series The Two-Headed Dragon–Energy/Water/Food Scarcity and Climate Change — the Top Ten Policies that Feed It; Two New Technologies (and One Old) that Could Enable us to Slay It and Save the Planet focuses on the unintended side effects of large dams and levee systems. It specifically discusses how they are causing serious environmental problems downstream that are becoming more damaging than the benefits that these dams and levee systems provide. In many ways this cautionary tale is applicable to many other technological and large scale engineering interventions into natural systems, especially when these technologies and engineered systems are not well understood.
