I spent 15 years living in the deep woods studying and thinking about how nature works and writing books such as the one you are reading. I lived in a school bus with an attached greenhouse. I used it as a scientific laboratory for evaluating things such as passive and active solar energy technologies, waste disposal (composting toilets), natural cooling (earth tubes), ways to save energy and water, and biological control of pests. It was great fun and I learned a lot. Since most of the world is urban I came out of the woods to find out more about this way of living.
Then no one can benefit from it, and that is the tragedy. One solution is to use free-access resources at rates well below their estimated sustainable yields by reducing population, regulating access to the resources, or both.

Governments have also enacted laws and international treaties to regulate access to commonly owned resources such as forests, national parks, rangelands, and fisheries in coastal waters.
8 United States The Netherlands The per capita ecological footprint is the amount of biologically productive land and water needed to supply each person or population with the renewable resources they use and to absorb or dispose of the wastes from such resource use. It measures the average environmental impact of individuals in different countries and areas. In other words, it is a measure of how much of the earth’s natural capital and biological income each of us uses. Bad news. Humanity’s ecological footprint per person exceeds the earth’s biological capacity to replenish renewable resources and absorb waste by about 15% (Figure 1-7, right).
