This radio broadcast discusses the findings of a conservationist who flew over of most of the continent of Africa in a small plane at low altitude, photographing the ground below every 20 seconds, to form a grid map. The flyover was intended to evaluate human impacts on African ecosystems, including wildlife, vegetation, and soil. The researcher, Dr, Michael Fay, points out that humans have penetrated very deeply into every single ecosystem in Africa that was visited, exhausting soils, vegetation, and water systems. He also discusses the need for greater natural resource management to locate the places where humans have already exceeded what the ecosystem can sustain. The broadcast is 7 minutes and 45 seconds in length.
