Document Summary
Environmental science: study of how the natural world works, how our environment affects us, and how we affect our environment. Natural resources: the various substances and energy sources we need to survive. Renewable natural resources: natural resources that are replenishable over short periods (ex. wind) Resource management: strategic decision making and planning aimed at balancing the use of a resource with its protection and preservation. Basic premise of renewable resource management is to balance the rate of withdrawal from the stock (harvestable portion) with the rate or renewal or regeneration. Nonrenewable natural resources: natural resources that are in finite supply and are depletable because they are formed much more slowly than we use them (ex. coal, natural gas, copper) Population growth affects resource use and availability. Impact on the environment is the product of population, affluence (level of consumption), and technology. Carrying capacity and the tragedy of the commons .
