| A | B |
|---|
| Aquaculture | the practice of raising fish and other water-dwelling organisms for food |
| Biodiversity | the number of different species in an area |
| Biogeography | the study of where organisms live |
| Captive breeding | the mating of animals in zoos or wildlife preserves |
| Clear-cutting | The process of cutting down all the trees in an area at once |
| Continental Drift | the movement of the Earth’s plates and the continents with them |
| Climate | Has an impact on the diversity of species as you travel from pole to pole. |
| Dispersal | the movement of organisms from one place to another. Can be caused by wind, water, or living things |
| Endangered Species | species in danger of becoming extinct in the near future |
| Environmental Science | the study of the natural processes in the environment and how humans affect them. |
| Exotic Species | an organism that is carried into a new location by people |
| Extinction | the disappearance of all members of a species |
| Fishery | an area with a large population of valuable ocean organisms |
| Habitat destruction | examples include; clearing forests to build towns or create grazing land. Plowing or filling in wetlands… |
| Habitat fragmentation | breaking larger habitats into smaller, isolated pieces, or fragments |
| Keystone species | a species that influences the survival of many other species in an ecosystem |
| Natural resource | Anything in the natural environment used by people |
| Non-point source pollution | Pollution generated by diffuse land use activities rather than from an identifiable or discrete facility. It is conveyed to waterways through natural processes, such as rainfall, storm runoff, or groundwater seepage rather than by deliberate discharge |
| Non-renewable resource | resources that used and the supply decreases, oil, coal. |
| Poaching | the illegal killing or removal of wildlife from their habitats |
| Point source pollution | pollution that is a single identifiable localized source of air, water, thermal, noise or light pollution. |
| Pollution | The contamination of the Earth’s land, water, or air. |
| Renewable resource | resources that are always available or naturally replaced in a relatively short time |
| Run-off | The overflow of fluid from a container. Rainfall not absorbed by soil. Eliminated waste products from manufacturing processes |
| Sediment | Material that settles to the bottom of a liquid |
| Selective cutting | Cutting down only some of the trees in a forest and leaving a mix of tree sizes and species behind |
| Sewage | waste matter carried away in sewers or drains |
| Sustainable yield | an amount of renewable resource such as trees that can be harvested regularly without reducing future supply |
| Threatened species | species that could become endangered in the near future |
