Document Summary
Environment: all external conditions, abiotic &biotic (nonliving &living), that affect an organism or group of organisms. Resources: naturally occurring substances that humans regard as useful or necessary. Depend on human perception, attitudes & behaviors, new technologies & prices. Renewable resources: capable of self-replenishing or can be replenished by human action. Non-renewable: once used are not replenished naturally or take hundreds to millions of years to replenish. Exhaustible (non-renewable) consumed by use, fossil fuels (renewability depends on use, levels &human investment) animals, plants, minerals, air & water quantity (naturally renewable of use) solar energy, tidal & wind power, water resources. Limited ability to make accurate, timely predictions of environmental impacts. A value change to less consumption & more recycling. A resolution to mineral exhaustion through price structure, product substitution, technological gains. A resolution of negative impacts by pollution controls & economic instruments (eg emission charges, carbon tax, congestion charge, tax on oil, tax on car batteries)
