Dependency Ratio | The number of old and young dependents who don't work compared with the working - age population. |
Life Expectancy | The average age that a person in a given population can expect to live. |
Replacement Rate | The total fertility rate needed for a population to replace itself. |
Total Fertility Rate | The average number of children a woman in a given population will have in her lifetime. |
Acid Rain | Rain that can damage the environment because it contains acid from factory smoke, and car exhaust. |
Nuclear Radiation | A form of energy that comes from nuclear radiations. Radiation has no smell but can be harmful. |
River System | A river and all that streams that flow into it. The streams flow into a river called Tributaries. |
Transboundary Pollution | Pollution that starts in one country and crosses boundaries into other countries. |
Stage 1 - ¨Low Population Growth¨ | In this stage, High death rates, high death rates result in little population change. All populations began at this stage |
Stage 2 - ¨Rapid Population Growth¨ | Birth rates remain high as the economic develops but the death rates fall as Food Supplies increase in healthcare improves. |
Stage 3 - ¨Slow Population Growth¨ | As the economy improves the birth rates drop. Death rates stay low. Population growth begins to slow down. |
Stage 4 - ¨No or Negative Population Growth¨ | In developed countries both birth rates and death rates drop to lower levels. As a result there is little or no population growth. Overtime birth rates may fall behind death rates. The result is a shrinking population. |
