Document Summary
99% of the next billion people will be born in regions that are least able to support them. Impact(i) on the environment is the interaction of: Population (p) = individuals need space, resources. Ef measure the amount of biologically productive land and water area required to produce the resources consumed and absorbed the water produced by an entity(individual, city,region,etc. ) By comparing consumption and productivity, the ef estimates the impact if consumption and waste on ecosystems. From the living planet index global ecological footprint has increased 190% in the last 50 years. Capacity of ecosystems to produce resources and to absorb wastes using current management schemes and extraction technologies. Actual physical area x and appropriate equivalence factor for each land type. A way of describing relative carrying capacity. Some call this period the anthropocene: a period of exploding human population and economic growth driving unprecedented planetary change through the increased demand for energy land and water.
