Q

precautionary principle

A

the idea that one should not undertake a new action until the ramifications of that action are well understood

biotechnology

A

the material application of biological science to create products derived from organisms. the creation of transgenic organisms is on type of biotechnology

Q

community-supported agriculture (CSA)

A

a system in which consumers pay farmers in advance for a share of their yield, usually in the form of weekly deliveries of produce

5
Q

life-cycle analysis

A

a quantitative analysis of inputs across the entire life cycle of a product-from its origins, through its production, transportation, sale, and use, and finally its disposal-in an attempt to judge the sustainability of the process and make it more ecologically efficient

6
Q

poaching

A

the illegal killing of wildlife, usually for meat or body parts

7
Q

genetic diversity

A

a measurement of differences in DNA composition among individuals within a given species

8
Q

ecosystem diversity

A

the number and variety of ecosystems in a particular area. on way to express biodiversity. related concepts consider the geographic arrangements of habitats, communities, or ecosystems at the landscape level, including sizes, shapes, and interconnectedness of patches of these entities

9
Q

species diversity

A

the number and variety of species in the world or in a particular region

10
Q

red list

A

an updated list of species facing unusually high risks of extinction. This list in maintained by the World Conservation Union

11
Q

species

A

a population or group of populations of organisms were member share certain characteristics and can breed freely with one another and produce fertile offspring. different biologists may have different approaches to diagnosing a species boundaries

12
Q

biodiversity (biological diversity)

A

the variety of life across all levels of biological organization, including the diversity of species, their genes, their populations, and their communities

13
Q

recombinant DNA

A

DNA that has been patched together from the DNA of multiple organisms in an attempt to produce desirable traits such as rapid growth, disease and pest resistance or higher nutrient content in organisms lacking those trairs

14
Q

habitat fragmentation

A

the process by which an expanse of natural habitat becomes broken up into discontinuous fragments, often as a result of farming, road building, and other types of human development and land use

15
Q

biophilia

A

an inherent love for and fascination with nature and an instinctive desire people have to affiliate with other living things defined by biologist E.O. wilson as “the connections that human beings subconsciously seek with the rest of life.”

16
Q

conservation biology

A

a scientific discipline devoted to understanding the factors, forces, and processes that influence the loss, protection, and restoration of biodiversity within and among ecosystems

17
Q

Endangered species act (ESA)

A

the primary legislation, enacted in 1973, for protecting biodiversity in the u.s. it forbids the government and private citizens from taking actions (such as developing land) that would destroy endangered species or their habitats and it prohibits trade in products made from endangered species

19
Q

convention on international trade in endangered species of wild fauna and fiora (cites)

A

a 1973 treaty facilitated by the in that protects endangered species so that their young can be bred and raised in controlled areas and subsequently reintroduced into the wild

20
Q

captive breeding

A

the practice of capturing members of a threatened species so that their young can be bred and raised controlled areas and subsequently reintroduced into the wild

21
Q

biodiversity hotspot

A

an area that supports an especially great diversity of species, particulary species that are endemic to the area

23
Q

ecological restoration

A

efforts to reverse the effects of human disruption of ecological systems and to restore communities to their condition before the disruption. The practice that applies principles of restoration ecology

24
Q

community-based conservation

A

the practice of engaging local people to protect land and wildlife in their own region
