Document Summary
Population growth in the absence of resource limitation. Overshoot and crash - population grows too fast, uses up all the resources, and thus population starts to crash. Export emigrants - part of the population moves somewhere else. Cc is the max number of plants, animals, bacteria, etc. than an environment can sustain. Per capita resource utilization (how much ___ do we all need) Human carrying capacity estimates are variable (1-40 billion) Populations that live without conflict with nature. Energy policy that minimizes pollution and risk. Minimization of the use of nonrenewable resources (leaving some for future generations) The global perspective is a recent idea. Remote regions are linked by atmosphere and water. Linked to declines in aquatic life and birds. O3 protects life from harmful uv rays. O3 destroyed by halogens (such as cfc), commonly used as refrigerants. Despite production primarily in the northern hemisphere, cfcs have created an ozone hole above.
