Dangers to the Natural Environment
| Term | Definition |
|---|---|
| Natural Environment | includes all living and non-living things occurring naturally on Earth. It includes the interaction of all living species, and is different from the built environment made or influenced by man |
| Population Growth | the rate of human population increase, which has increased greatly since about 1950; has led to a greater demand for natural resources |
| Urbanization | when people move from rural (farm) areas to urban areas (cities), making the cities and built-up areas larger |
| Industrialization | the change from making products by hand to making products in factories; often leads to larger cities and more pollution |
| global influences | things affecting the entire planet, including its weathers and ecosystems |
| Land development | changing land which was in its natural state by building farms, factories, or homes, etc. |
| eliminate | to get rid of, kill off, or destroy |
| habitat | the place where an organism lives; it must provide food, water, shelter, and mates (a place to reproduce) |
| Green Revolution | this began in the 1960s and was an attempt to increase food production worldwide through the increased use of fertilizers, pesticides, and new strains of crops |
| Pesticide | a chemical that kills insects or small animals that hurt crops or livestock |
| New Strains of Crops | new types or variants of crops that grow better, faster, and / or at a higher rate per acre |
| Higher Yields of Crops | when more crops can be successfully grown on the same amount of land |
| Famine | an extreme shortage of food that causes people to be extremely hungry; when lots of people starve to death |
| Soil Erosion | when top soil washes away, causing the land to be unproductive |
| localized | limited to a particular place or area |
| Natural Resources | plants, trees, minerals, and fresh water found in nature and useful to humans |
| Hydrocarbon | simple organic compounds made of only carbon and hydrogen, they are often used as fuel in the form of coal and natural gas |
| emission | when something is discharged or sent out, especially into the atmosphere |
| Carbon Dioxide | a natural occurring compound made of one carbon and two oxygen atoms; essential for plant life |
| Fossil Fuels | fuels made from buried dead organisms; usually refers to coal, oil, and natural gas |
| Acid Rain | made when sulfur dioxide and nitrous-oxide laden gas emissions from factories and cars mix with moisture in the air; it increases acid levels and damages forests and some fish in freshwater lakes |
| Ozone Layer | a thin protective layer in the atmosphere that protects people and animals from the sun’s cancer-causing ultraviolet radiation |
| Greenhouse Effect | when atmospheric gases such as water vapor, carbon dioxide, and methane absorb or trap heat radiated from the Earth’s surface, increasing Earth’s near surface temperatures |
| Sun's Ultraviolet Rays | short wavelength radiation from the sun that is invisible to humans, and which can cause sunburn and skin cancer |
| Chlorofluorocarbons (CFCs) | gases used in aerosols, air-conditioning, refrigerators, and foam packaging; their use may be destroying the ozone layer |
| Kyoto Protocol | In 1992, many nations of the world signed this agreeement designed to reduce greenhouse gases emitted by each country |
| Recycling | reusing materials in order to save natural resources |
| opt | to make a choice to do something; to pick something |
| Hybrid Cars | a car with both a gasoline powered motor and an electric motor; they save gas and pollute less |
| Alternative Sources of Energy | a source of energy that is not a fossil fuel; typically refers to nuclear, wind, or solar power |
| Renewable Energy Sources | sources of energy that are continuously replenished or replaced; typically refers to water, wind, solar, geothermal, or biomass energy sources |
| Solar power | converting sunlight into electricity to be used as a power source |
| Wind power | converting wind into a useful power source, typically electricity |
| Nuclear energy | using the process of nuclear fission (splitting atoms of uranium) to generate heat used to power steam turbines which generate electricity |
| Nonrenewable Energy Source | an energy source that does not replace itself faster than humans use it up, typically refers to fossil fuels and metal ores to include uranium |
