Pros

________: allows animals to graze on grass during their entire lifecycle, tends to be free from antibiotics, .organic waste from animals acts as fertilizer.

Cons

________: tend to be crowded, animals are fed grains, feedlots generate a large amount of organic waste can contaminate ground and surface water.

CAFOs

________- concentrated animal feeding operations.

Area

________ used by everyone but regulated by no one.

Mechanization

________- pros: efficient $, easy cons: fossil fuel uses, combustion, extraction.

Monoculture

________- pros: easy, fertilizer, same pests cons: 1 plant type, loss of biodiversity, habitat, genetics.

Chemical

AP Environmental Science

________: Unit 5 Review- Land and water Use.

Physical

________- barriers that protect crops.

Suggests that individuals

________ will use shared resources in their own self interest rather than keeping with the common good, resulting in resource depletion.

Crops

________ can be genetically engineered to increase their resistance to pests and disease, using genetically modified ________, this can lead to loss of genetic diversity.

Biological

________- introduction of natural pest predators.

Irrigation

________- pros: maximum yield, customize cons: deplete freshwater.

Artificial pesticide

________- pros: high yield, easy cons: health, evolution of pests.

Artificial fertilizer

________- pros: high yield, easy cons: runoff, eutrophication.

Furrow irrigation

________- involves cutting furrows between crop rows and filling them with water, inexpensive about ⅓ of the water is lost.

Flood irrigation

________- involves flooding an agricultural field with water, about 20 % of the water lost to evaporation and runoff.

Spray irrigation

________- involves pumping groundwater into spray nozzles across an agricultural field, only ¼ or less of the water lost to evaporation or runoff, more expensive and requires more energy to run.

Pros

________: less expensive than other methods, which can keep costs to consumers down.

Cons

________: requires large areas of land, meat produced is more expensive for consumers.

Cons

________: fish that escape can compete or breed with wild fish, disease incidences, wastewater.

Pros

________: highly efficient, requires only small areas of water, and requires little fuel.
