What is a HORIZON
100
The area used to raise large numbers of animals (mostly pigs, chickens and turkey) bred to gain weight quickly. They are usually given growth hormones and antibiotics.
What are FEEDLOTS or CAFOs (Concentrated Animal Feeding Operations)
100
What would happen if there were multiple fish kills from pesticide runoff. Or wild predators were allowed to be killed in order to protect livestock. Or grasslands, forests and wetlands were loss due to cultivation?
LOSS IN BIODIVERSITY
100
dichlorodiphenyltrichloroethane
What is DDT
200
A method of growing plants by exposing their roots to a nutrient-rich water solution.
What is HYDROPONICS
200
The movement of soil components, especially surface litter and topsoil, from one place to another by the actions of wind and water.
What is SOIL EROSION
200
In 2010, half of all the fish eaten in the world were produced this way. The practice of raising marine and freshwater fish in freshwater ponds or underwater cages in coastal or open ocean waters.
What is AQUACULTURE
200
What part of the environment does erosion, salinization, waterlogging, and desertification affect?
SOIL
200
She wrote the book Silent Spring which talked about the harmful effects of pesticide on wildlife and humans.
Who is Rachel Carson
300
Bananas, soybeans, sugarcane, coffee, palm oil, and vegetables on large monoculture plantations, mostly for export to more-developed countries.
What is CASH CROPS
300
A soil degradation process in which repeated applications of irrigation water in dry climates can lead to the gradual accumulation of salts in the upper soil layers.
What is SALINIZATION
300
The industrialization of food production has been made possible by the availability of this product. Mostly from the nonrenewable source of it.
What is ENERGY
300
What part of the environment does aquifer depletion, pollution from pesticides and fertilizers, and algal blooms occur in?
WATER
300
Name an advantage of using conventional chemical pesticides.
-Saves lives
-Increase food supplies
-Profitable
-Work fast
-Safe if used properly
400
Since 1950, this process has led to 88% of the increase in global food production from using high-input industrialized agriculture to increase crop yields.
What is the GREEN REVOLUTION
400
When the productive potential of topsoil falls by 10% or more because of a combination of prolonged drought and human activities such as overgrazing.
What is DESERTIFICATION
400
A second gene revolution is made possible through this type of organism. It involves altering an organism's genetic material through a process called gene splicing.
What is GMOs (Genetically Modified Organisms)
400
Carbon dioxide emission from fossil fuel use, nitrous oxide emission from use of inorganic fertilizers, and methane emission by cattle.
What are GREENHOUSE GASES
400
Name a disadvantage to using conventional chemical pesticide.
-Promotes genetic resistance
-Kills natural pest enemies
-Pollutes the environment
-Can harm wildlife and people
-Are expensive for farmers
500
A pesticide that is toxic to many pests, but also to beneficial species. An example would be DDT.
What is BROAD-SPECTRUM AGENTS
500
Is topsoil a renewable resource?
YES
500
In the United States, industrialized farming has evolved into this. Where a small number of giant multinational corporations increasingly control the growing, processing, distribution, and sale of food in U.S.
What is AGRIBUSINESS
500
Name one human health problem that could arise from industrialized food production.
-Nitrates in drinking water (blue baby).
-Pesticide residues in drinking water, food, and air.
-Contamination of drinking and swimming water from livestock wastes.
-Bacterial contamination of meat.
500
Name an alternative to conventional pesticide use.
-Fool the pest
-Provide homes for pest enemies
-Implant genetic resistance
-Bring in natural enemies
-Use insect perfumes
-Bring in hormones
