Transition

"The bottom line for our species is that because of population growth and the fivefold economic expansion since 1950, the environmental demands of our economic system now fill the available environmental space of the planet. This has brought us to a historic transitional point in the evolutionary development of our species from living in a world of open frontiers to living in a full world—in a mere historical instant. We now have the option of adjusting ourselves to this new reality or destroying our ecological niche and suffering the consequences.
