| Question | Answer |
|---|---|
| what are human activities that effect the biosphere? | hunting,gathering,agriculture,industry,and urban development |
| Agriculture | the practice of farming |
| green revolution | the development of highly productive crop strains and the use of modern agricultural techniques to increase yields of food crops |
| monoculture | farming strategy in which large fields are planted with a single crop year after year |
| renewable recources | a resource that regenerates and that is replaceable |
| nonrenewable recources | resources that can not be replenished by natural process |
| sustainable recources | using natural resources at a rate that do not deplete them |
| soil erosion | wearing away soil by water and wind |
| desertification | poor farming practices, overgrazing, and drought that makes productive land into desert |
| deforestation | destruction of forest |
| aquaculture | the raising of aquatic organisms for human consumption |
| smog | mixture of chemicals that occurs as gray brown haze in the atmosphere |
| pollutant | harmful materials that can enter the biosphere |
| acid rain | containing nitric and sulfuric acid |
| biodiversity | the variety of organisms in the biosphere |
| ecosystem diversity | variety of habitats, |
| species diversity | number of different species in the biosphere |
| genetic diversity | sum total of all different forms of genetic information of organism on earth today |
| extinction | disappearance of a species |
| endangered species | species in which population size is rapidly going down and will be come extinct if the trend continues |
| habitat fragmentation | splitting of organisms into small fragments |
| biological magnification | increasing of concentration of harmful substance in organisms at higher trophic level in a food chain or food web |
| conservation | wise management of natural resources, including the preservation of habitats and wildlife |
| ozone layer | atmospheric layer in which ozone gas is relatively concentrated |
| global warming | increase in the average temp on earth |
| What are environmental goods and services classified as? | Renewable or nonrenewable |
| what do human activies affect? | The quality and supply of renewable resources |
| agriculture | the process of farming |
| monoculture | farming strategy in which large fields are planted with a single crop year after year |
| green revolution | the development of highly productive crop strains and the use modern agricultural techniques to increase yield of food crops |
| renewable resources | a resource that can regenerate quickly and that is replaceable |
| Nonrenewable recourses | resources that can regenate quickly that is replaceable |
| sustainable development | Using Natural Resources at a rate that does not deplete them |
| soil erosion | wearing away of surface soil by water and wind |
| desertification | in areas with dry climate, a process caused by a combination of poor farming practices, overgrazing and drought and turns productive land into desert |
| deforestation | destruction of forest |
