Figure 1-4: Degradation of normally renewable natural resources and services in parts of the world, mostly as a result of rising population and resource use per person.
Figure 1.8: Natural capital use and degradation: total and per capita ecological footprints of selected countries (top). In 2003, humanity’s total or global ecological footprint was about 25% higher than the earth’s ecological capacity (bottom) and is projected to be twice the planet’s ecological capacity by 2050. Question: If we are living beyond the earth’s ecological capacity, why do you think the human population and per capita resource consumption are still growing exponentially? (Data from Worldwide Fund for Nature, Global Footprint Network)
Figure 1-7: Connections: simple model of how three factors—number of people, affluence (resource use per person), and technology—affect the environmental impact of populations in developing countries (top) and developed countries (bottom). While many people in affluent countries over-consume, many poor people in developing countries suffer from not having enough resources.
