Term
Green Revolution 2.0
Definition
Focuses on the production of geneticaly modified organisms to increase crop productivity or create new varities of crops
Term
The use of fertilizer can benefit and cause problems. (example)
Definition
An increase in productivity can cause eutrophication. The increase in productivity comes from fertilizer. Once it rains, the runoff from the crops contains fertilizer in it, which is polluting the land. This causes a blockage in sunlight, therefore there is no ability for photosynthesis. If there is no photosynthesis, the organisms are no longer getting oxygen and they are not going to be able to survive.
Term
Pesticide Resistant Cycle
Definition
When a plant is first exposed to a pesticide, it is more than likely to destory it. The pests that do survive, will reproduce, and those survivors who are resistant to the pesticide, will reproduce and they will carry on the gene of being resistant. Over time, the the amount of resistant pesticides will contaiminate a crop, and will damange the crop from being put out on the market.
Term
Integrated Farming
Definition
This farming technique is similar to the idea of a food chain. With all the organisms providing fertilizer, the plants in the water are able to grow at a more steady and increase in size. The symbiotic bacteria that came from the plant, produces a fertilizer that is benefitial to the rice. Once he realized he was getting natural fertilizer from the animals, he realized he was saving money and not longer needed to buy synthetic fertilizer.
Term
Feed Conversion Rate Concept
Definition
The amount of food produced per unit of food the animal is consuming is called feed conversion rates. The idea of animals producing in mass quantities is less healthier than an animal who is producing at a slower rate and not as much. When an animal isnt as exposed to fertilized plants, the meat/dairy they produce is healther and contains less pesticides. The net gain idea is having animals eat products that humans can consume on their own, and them breaking it down and producing the food we can eat.
Term
Sustainable Agriculte Pros/Cons
Definition
There are many different methods of sustainable farming. Sustainable farming is benefital because it protects the soil, and produces better products. The tradeoffs for sustainable and organic agriculture are more expensive and produce less food but they are less hazardous to the environment. The most important factor of sustainable farming is it reduces soil erosion.
Term
Organic Agriculture
Definition
Farming that does not use synthetic fertilizer, pesticides, or other chemical additives.
Term
CAFO
Definition
Many meat or dairy animals are reared in confined spaces, maximizing the number of animals that can be grown in a small area.
Term
Eutrophication
Definition
Nutrient enrichment of an aquatic ecosystem that stimulates excess plant growth and disrupts normal energy uptake and matter cycles.
Term
Feed Conversion Rates
Definition
How much edible food is produced per unit of feed input.
Term
Food Miles
Definition
The distance food travels from its site of production to the consumer.
Term
GMOs
Definition
(Genetically Modified Organisms) Organisms that have had their genetic info.
Term
Green Revolution
Definition
Plant-breeding program in the mid-1900s that dramatically increased crop yields and led the way for mechanized, large-scale agriculture.
Term
Key Concept 1
Definition
Fertilizer run-off from crop production enters waterways and causes algae and other aquatic plants to grow into massive blooms. The blooms block sunlight from reaching underwater, shutting down underwater photosynthesis and causing oxygen-poor regions.
Term
Key Concept 2
Definition
Integrated farming, such as Furuno's rice paddies, have more success and are more environmentally beneficial than monoculture farming. Furuno's farm is a self-regulating and multiple-species system that produces increased root crowns of rice.
Term
Key Concept 3
Definition
Monocrop agriculture has many disadvantages such as contributing heavily to global warming and being expensive. Many monocrops are not locally adapted so the farmers have to add external inputs (water, pesticides, and fertilizer) to the farm. This is not only expensive but it depletes resources from other areas as well.
Term
Key Concept 4
Definition
Critics say that organic farming and industrial agriculture will not produce enough food to feed 10 million people, so scientists have begun working on genetic engineering. Genetic engineering involves manipulating genes to increase productivity or to make it possible to grow crops in places they normally wouldn't.
Term
Key Concept 5
Definition
GMOs are found in more than 75% of processed food in the States but other countries are opposed to GMOs because of the possible health and environmental consequences. Genes introduced into domestic crops could escape into the natural world and be incorporated into other plants for which they were not intended.
Term
Monoculture
Definition
Farming method in which one variety of one crop is planted, typically in rows over huge swaths of land, with large inputs of fertilizer, pesticides, and water.
Term
Sustainable Agriculture
Definition
Farming methods that do not deplete resources, such as soil and water, faster than they are replaced.
Term
Transgenic Organism
Definition
An organism that contains genes from another species.
Term
Green Revolution (concept)
Definition
The Green Revolution was a coordinated, global effort to eliminate hunger by improving crop performance and bringing modern agricultural technology to developing countries.
Term
Eutrophication (term)
Definition
Process in which excess nutrients in aquatic ecosystems feed biological productivity, ultimately lowering the oxygen content in the water
Term
Monoculture Farming (term)
Definition
Farming method in which one variety of crop is planted, typically in rows over huge swaths of land, with large inputs of fertilizer, pesticides, and water.
Term
Feed Conversion Rates (term)
Definition
How quickly and efficiently any given animal converts the food it eats into body mass (that we then eat).
Term
Sustainable agriculture (term)
Definition
Farming methods that do not deplete resources, such as soil and water, faster than they are replaced.
Term
Green Revolution 2.0 (concept)
Definition
Involves manipulating genes to increase productivity or to make it possible to grow crops in places they normally wound't-like marginal land, in drought-plagued regions, or on fields doused in pesticide and herbicide.
Term
Genetically modified organisms (GMOs) (term)
Definition
Organisms that have had their genetic information modified in a way that does not occur naturally.
Term
Organic Agriculture (term)
Definition
Farming that does not use synthetic fertilizer, pesticides, or other chemical additives like hormones (for animal rearing)
Term
Food Miles (term)
Definition
The distance a food travels from its site of production to the consumer.
Term
Concentrated Animal Feeding Operation (CAFO) (concept)
Definition
Lifestock are raised in confined spaces, with a focus on raising as many animals in a given area as possible. They are fed a nutrient rich diet, and since they are kept in small spaces it is easier to harvest their waste for fertilizer.
Term
Transgenic Organism (term)
Definition
An organism that contains genes from another species.
Term
Crop Rotation (term)
Definition
Planting different crops on a given plot of land every few years helps maintain soil fertility and reduces pest outbreaks since pests from the year before (or their offspring) will not find a suitable food when they emerge in the new season.
Term
Reduced Tillage (term)
Definition
Planting crops into soil that in minimally tilled reduces soil erosion and water needs (it reduces water evaporation). It also requires less fuel because of less tractor use.
Term
Trade-offs of Organic Farming (concept)
Definition
For consumers, some advantages include no pesticide residue on produce and less risk of exposure to antibiotic resistant bacteria, and some disadvantages are that fruits and vegetables may have more clemishes on them, as well as them being more expensive. For the farmer/the environment the advantages are fewer and less costly inputs and less potential for water pollution, and disadvantages are that it is more labor intensive and cros native to the area or suitable for the climate do best so may not be able to grow all crops in all areas.
Term
Bringing home changes to help the envitonment
Definition
Changing your food choices is one big way to help the envitonment as well as boost your personal health. Supporting local farmers, reducing the amount of animal products you eat, as well as buying organic products will also help with the environmental issues.
