Unit 5 Vocab Flashcards
the cultivation of aquatic organisms such as fish, shellfish, and aquatic plants in controlled environments
aquaculture
killing unwanted species of marine life
bycatch
Clearcutting
Green Revolution
Pesticides
Selective Breeding
Gene Revolution
Genetic Engineering
clearcutting and burning of a forested area in order to make way for agricultural fields. The ash produced from the burning of the original organic matter provides short-term fertilization and the plot is left almost weed-free due to the burning. contributes to carbon dioxide emissions through the burning of organic matter and erosion due to (no longer protected from rain or held in place by old-growth plant roots)
Slash and Burn
Tillage
used to control unwanted fungi
Fungicide
Flood Irrigation
irrigation through large rolling or stationary sprinklers
Spray Irrigation
irrigation through small holes in hoses laid by the roots of plants, directly on the soil. This is the most efficient of the options, losing approximately 5 % of the water used to evaporation
Trickle/Drip Irrigation
Pivot Irrigation
cuts grooves, or furrows, between rows of plants, filling them with water.
Furrow Irrigation
Pesticides Treadmill
also known as feedlots, are an efficient farming method that quickly plumps up livestock to turn them around for meat production
CAFOs
a farming method where livestock can roam the land and not be confined. It takes longer for them to reach the point of meat production as their diet consists of grazing the pasture. The animals rarely get sick, and if so, the farmer will administer antibiotics. It is considered an economical way of meat production as it requires little to operate.
Free Range
regularly rotate the livestock among different pastures to avoid the possibility of overgrazing
Rotational Grazing
Overfishing
Tragedy of the Commons
Surface Mining
Tailing Ponds
