Document Summary
Nonrenewable (oil, coal)--- can increase/decrease depending on rate of usage recycleable (e. g. metals) --old landfill sites being mined by companies finite in a physical sense, but in a pragmatic sense can change. Perpetual (solar, tides) renewable (fish, trees)- rate of extraction mustn"t exceed rate of regeneration (otherwise becomes stock) caveat/proviso/conditional statement- renewable but it depends on management! Renewable resrouces have been exploited and made extinct e. g. cod on the east coast of canada cars are recycled. In japan must be made so they can be easily recycled. Efficiency- we don"t want the oil, we want the work! Technology can expand a resource e. g. make 1 unit of oil last longer. Bonua on the final- landlock countries surrounded by landlock countries. Most likely, bands of uncertainty (world population projection) Exponential growth in a 65 year period 2. 5-7. 3 billion. Differential population increase- developed (oecd organization of economic cooperation and development) countries not growing.
