Document Summary
Chapter 1 pg 6-10: natural resources: the substances and energy sources we need to survive, they are finite. Balance the rate of withdrawal with the rate of renewal: the stock is the harvestable portion of the resource. If it is being withdrawn faster than it can renew, eventually it will be depleted: non-renewable resources (fossil fuels, mineral deposits) are finite supply and are depleted, because they are formed so slowly (sometimes 100 million years). Just by withdrawing from the stock we are depleting the source: we rely on many minerals to make common items, we mine these resources instead of harvesting them. Transition from nomadic hunter gatherer ways to a agricultural way of life: third: industrial revolution: mid 1700s, shift from rural life and manufacturing to urban society powered by fossil fuels. Beginning of industrial scale pollution and social problems. Air quality declined, water quality declined because of dense populated cities & coal usage: fourth: medical-technological revolution: today"s world.
