aquaculture
the raising of aquatic organisms for food in controlled environments
Bacillus thuringiensis (Bt)
a naturally occuring soil bacterium that produces a protein that kills many pests, including caterpillars and the larvae of some flies and beetles
biocontrol (biological control)
the attempt to battle pests and weeds with organisms that prey on or parasitize them, rather than by sing pesticides
biotechnology
the material application of biological science to create products derived of organisms
feedlots
a huge barn or outdoor pen designed to deliver energy rich food to animals living at extremely high densities.
food security
an adequate, reliable, and available food supply to all people at all times
gene banks (Seed banks)
a storehouse for samples of the world’s crop diversity
genetic engineering
any process scientists use to manipulate an organism’s genetic material in the labby adding, deleting, or changing segments of its DNA
genetically modified(GM)organisms
an organism that has been geneticall engineered using a technique called recombinant DNA technology
green revolution
an intensification of the industrialization of agriculture in the developing world in the latter half of the 20th century that has dramatically increased crop yields produced per unit area of farmland
integrated pest management (IPM)
the use of multiple techniques in combination to achieve long-term suppression of pests, including biocontrol, use of pesticides, close monitoring of populations, habitat alteration, crop rotation, transgenic crops, alternative tilling methods, and mechanical pest removal
malnutrition
the condition of lacking nutrients the body needs, including a complete complement of viatmins and minerals
organic agriculture
agriculture that uses no synthetic fertilizers or pesticides but instead relies in boilogical aproaches such as composting and boicontrol
overnutrition
a condition of excessive food intake in which people receive more tahn their daily caloric needs
pesticides
an artificial chemical used to kill insects, plants, or fungi
pollination
an interaction in which one organism (for example, bees) transfer pollen (male sex cells) from one flower to the ova (female cells) of another, fertilizing the female flower, which subssequently grows into a fruit.
precautionary principle
the idea that one should not undertake a new action until the ramifications of that action are well understood
recombinant DNA
DNA that has been patched together from the DNA of multiple organisms in an attempt to produce desirable traits in organisms lacking those traits
sustainable agriculture
agriculture that does not deplete soils faster than they form them
transgenes
a gene that has been extracted from the DNA of one organism and transferred into the DNA of an organism of another species
transgenic
describes an organism that contains DNA from another species
undernourished
a condition of insufficient nutrition in which people receive less than 90% of their daily caloric needs
