In his work, Island Civilization, Roderick Frazier Nash discusses the prospect of humans changing their way of life as a whole in order to minimize their impact on nature. He proposes that humans live in small “islands” that were self-sufficient and minimized their impact on nature by being scattered throughout the world and only impacting a tiny portion of the planet. This plan would require the reduction of the human population to less than a quarter of its current size and the relocation of the remaining members of society, and through these two processes would in a way take away part of the freedom that the humanity as a whole currently enjoys.
The prospect of Island Civilization is marvelous in theory and could very well be the solution to the problem of man destroying nature but I do not believe it is one that would work from a practical standpoint. As described by Nash, the rewards to transitioning to an Island Civilization would be great:
“The result could be the conservation biology dream. The frontier reappears, and this time it is permanent. Rivers are full of salmon and the deer and antelope play on the plains. The big predators are back too and, without human interference, perhaps evolving into some of the Pleistocene megafauna we never got to know. As we were before herding and agriculture, say 10,000 BC, humans in the year 3010 are once again good neighbors in the ecological community. Homo sapiens is healthy and enjoying its version of liberty and the pursuit of happiness and so are all the other components of the natural world.”
Despite the incredible gains that could be made for the whole of the planet, I still believe that a significant portion of humanity would be opposed to this change by the desire to protect their current freedoms and luxuries. Many freedoms would have to be given up and a prime example is given by Nash himself as he states, “If you wanted to ski you’d chose to live on the island built into, say, part of the Alps.” If someone enjoyed skiing but did not want to live on a mountain, then they would lose their ability to readily and easily ski. Due purely to the reduction of freedoms and the nature of man when proposed with the reduction of those freedoms, I do not consider the prospect of Island Civilization to be a practical solution.
From a theoretical standpoint in which war, land conflicts, and border disputes are not present, the remaining human population embraces fully the consequences, good and bad, of Island Civilization, and all that remains of civilization is utopian in nature, the prospect of Island Civilization is a perfect solution with countless benefits. However, in a realistic society where there is resistance to change in some form, the prospect of Island Civilization is not a practical solution to the problem of mankind's ravaging of nature. In the future, if mankind as a whole has went through a form of enlightenment in which they have realized the severity with which mankind has destroyed nature, then Island Civilization may become a practical and very real solution to this problem. However, until this occurs there is not only the problem of mankind destroying nature, but mankind being too absorbed into the self in order to realize the destruction of nature and the prices of their luxuries. Another solution that is able to accommodate both those who are willing to sacrifice for a utopia and those who aren't may be found but until then, the nature of mankind changing to accommodate the transition to Island Civilization is the closest thing that exists to a solution to the issue of mankind destroying nature.
