4890066539Convention on Biological Diversity (1992)3 objectives: conserve biodiversity, sustainably use biodiversity, share benefits from the commercial use of genetic resources such as pharmaceutical drugs20
4890066540Criteria for choosing protected areaswe must consider how close to another area they should be, how large the area is, and the amount of edge habitat the area contains.21
4890066541Edge habitatthe area where two different communities come together, typically forming an abrupt transition. Ex./ a grassy field meeting a forest22
4890066542Biosphere reservesprotected areas consisting of zones that vary in the amount of permissible human impact23
4890066543Theory of island biogeographylarger and closer "islands" have greater diversity24
