Vocab
Happens when too much of a shared resource is used up at the same time
Tragedy of the commons
A method of mining which strips soil and rock to expose ore. Usually yields coal or sand.
Strip mining
The use of machines in agriculture
mechanization
Dumps water over the land and lets it go wherever. Most water is lost to evaporation
Flooding
Greenhouse gas released by cows
methane
People's ability to access sufficient, safe, nutritious food to maintain a healthy and active life.
Food Security
Name at least 3 metals used for making batteries for electronic devices.
Cobalt, lithium, manganese, nickel
disrupts the nitrogen cycle, dissolves easily
furrow
Monoculture
Totals the number of fish allowed to be caught and distributes quotas to individual fishers or fishing companies.
Individual Transferable Quotas (ITQs)
Name at least 2 negative effects of mining that are not pollution.
Soil erosion caused by loss of vegetation, loss of biodiversity, respiratory issues
Crops that are crossbred to make them more resistant to their climate/produce more yield
High yield variety crops, GMO's are technically different but still earn point i feel
Using large sprinkler systems to distribute water to the plants. Still water inefficient, but isn't as bad as other methods.
Spray
Happens when too much animals feed on a particular part of the land
overgrazing
A cost or benefit of a good or service that is not included in the purchased price of the food or service.
Externalities
Mining that involves scooping up polymetallic nodules not found on Earth's surface
Deep-sea mining
Chemicals used to poison bugs that may harm crop yield
Pesticides
Involves a hose network that is placed close to plants. Most water efficient as only small amounts of water is used when it is needed. Most expensive method of irrigation
Drip
Big systems that raise animals for slaughter in confined areas, relatively cheap
Concentrated Animal Feeding Operation
The maximum amount that can be harvested from a resource without compromising the future availability of that resource.
Maximum Sustainable Yield
An expensive method of mining that uses elevators, tunnels, and drills to hoist people down into the mining site. Very expensive and yields rarer materials like diamond and gold.
subsurface mining
Eco friendly alternatives to pesticides are called this
Integrated Pest Management
Happens when water evaporates after irrigation. Evaporating water brings the salt from the soil up to the surface
Salinization
Considered a more humane way to raise animals, lowers their stress and is more expensive to do because of the large amount of land that is required
Free range grazing
