Bøger af Mark (Mark Nelson) Nelson

Mark Nelson, PhD, has worked for several decades in closed ecological systems research. As one of eight brave souls enclosed in the pioneering Biosphere 2 experiment for two years in 1991-1993, Nelson learned fi rst hand how essential the proper use of human waste is to the health of the planet. This realization, combined with his lifelong love aff air with constructed wetlands, led to the development of Wastewater Gardens, an ecological way to treat human waste and preserve water quality.

Mark Nelson takes us on a global expedition to learn how we are wasting the world''s dwindling supplies of fresh water by flushing away a very valuable resource, our own human wastes!  A founding director of the Institute of Ecotechnics, Dr. Nelson has worked for several decades in closed ecological system research. As one of eight brave souls enclosed in the pioneering Biosphere 2 experiment, he realised how essential the proper re-use of human waste is to the health of the planet. This led to what Dr. Nelson calls a life-long love affair with constructed wetlands, where he discovered an important solution to some of our trickiest global dilemmas: Wastewater Gardens. While the problems covered in this book are very serious, Dr. Nelson''s approach to the subject makes for a delightful, down-to-earth read.
