Classification of Resources Nonrenewable/Exhaustible Resources Depletable & not renewable in human time scales Perpetual Resources Essentially inexhaustible or can be replenished rapidly Potentially Renewable Resources May be replenished or renewed if not depleted or degraded excessively Classification of Resources - Examples Air, water, soil, & wildlife are typically classified as renewable, but actually are only potentially renewable, since they can be depleted Resources Perpetual Nonrenewable Direct solar energy Winds, tides, flowing water Fossil fuels Metallic minerals (iron, copper, aluminum) Nonmetallic minerals (clay, sand, phosphates) Renewable Fresh air Fresh water Fertile soil Plants and animals (biodiversity) Slide 6 Nonrenewable Resources - Fossil Fuels & Minerals Physical Depletion vs. Economic Depletion Mitigating Resource Scarcity Technological Change, Exploration, Recycling, Reuse Potentially Renewable Resources Fish & Animals Carrying Capacity (P*) - Maximum Sustainable Population Sustainable Resource Harvest (SRH) - Amount Harvested Forever at Given Population Level Maximum Sustainable Yield (MSY) - Maximum of SRH Population Population (millions) P 40 30 20 10 o 10 20 30 40 50 60 70 80 Time (Months) T Carrying Capacity - Maximum Sustainable Population Population (millions) P 40 30 P* = 39 20 10 o 10 20 30 40 50 60 70 80 Time (Months) T Growth Growth (millions) G 4 3 P* = 39 2 1 o 5 10 15 20 25 30 35 40 Population (Millions) P Growth Growth (millions) G 4 3 2 1 o 5 10 15 20 25 30 35 40 Population (Millions) P Sustainable Resource Harvest (SRH) Growth (millions) G 4 If P = 10, G = 1.8 At P = 10, SRH = 1.8 3 2 1 o 5 10 15 20 25 30 35 40 Population (Millions) P Maximum Sustainable Yield (MSY) Growth (millions) G 4 3 2 1 MSY = 3.2 PMSY= 20 o 5 10 15 20 25 30 35 40 Population (Millions) P ...
