book buisman humanity is not a plague back

'I‘In this essay, Buisman sharply analyzes some of the problems facing mankind, such as fresh water shortages, whilst overturning several clichés and offering unexpected, positive solutions. Overpopulation is not the problem; the effects of our actions on the rest of the world have a much greater impact. “Back to nature”’ is not the solution, nor is an overreliance on science and innovation. Large-scale technologies could even increase our problems. It seems that the growth of humanity will depend on the growth of our consciousness.’

From the book cover:

‘Time and again we humans have to realize that the countless interactions and dependencies in nature are too complicated for us to fully understand. This fact makes it often impossible to predict all the consequences of a particular intrusion into nature, and it is not surprising that many well-intentioned technologies ultimately did more harm than good.
It is my vision that companies should define their innovation strategies to mimic nature, or as much as possible to be in harmony with nature – an approach I call “natural technology.” It therefore seems important to me to imitate nature as much as possible when it comes to health, energy, water and food.
The Austrian naturalist Viktor Schauberger had similar ideas over 80 years ago, and with his invention of “water vitalization,” Austrian inventor and water researcher Johann Grander is a perfect example of how natural technology is not only possible, but also socially and commercially successful.
IPF/Grander is unique in the development of nature-based technology and innovation strategy, making it a world leader in sustainable, physical water treatment.
