- aquaculture?
- fish farming
- shaft mining?
- rocks containing metals are mined from underground
- main use of fresh water in the world
- agriculture (73%)
- benefits of aquaculture
- supplies and growing demand for fish, constant quality, job creation
- benefits of composting
- is rich in nutrients and good for growing plants.
- problems with fishing
- over fishing -> low fish stocks, over fishing, species extinction, loss of jobs
- main use of fresh water in canada
- thermal power generation, manufacturing, municipal, agriculture, mining
- drawbacks of incineration
- burning garbage produces acid gases
- drawbacks of strip mining
- alot of waste products, alot of water needed, ugly scar, loss of animal homes.
- benefits of geothermal energy
- clean + reliable, provides jobs, price is stable
- economic benefits of Clearcutting
- creates jobs, provides wood and paper, safer
- main use of fresh water in the home
- showers/bath, toilet flushing, laurdry, kitchen/drinking, cleaning
- drawbacks of landfills
- contamination of groundwater
- monoculture?
- the cultivation of a single type of trees in an area
- drawbacks of fossil fuels
- oil spills (harms wildlife), expensive to pump from ground, dangerous, pollution
- benefits for strip mining
- less dangerous, less expensive, easier to operate.
- some threats to water in the world
- fresh water shortages, pollution, global change (rising sea levels)
- benefits of recycling
- less raw materials, decreased landfill space, less enviroment impact
- enhancement?
- a program to stop and reverce the decline of fish stocks, clean damaged streams
- benefits of nuclear energy
- there is lots of it, doesnt cause disaster
- how it improves the health of the forest
- reduced disease, infestation, reduce fires
- benefits of agriculture
- creates jobs, necessary for food
- strip mining?
- many rocks containing useful metals are mined from surface
- drawbacks of aquaculture
- bad farming practises, habitat loss, pollution from farms contaminate surrounding waters.
- drawbacks of open dump
- alot of flies, rats. run-off solid waste is untreated
- silviculture?
- the development and care of forests
- benefits of incineration
- recyclable material seperated
- benefits of fossil fuels
- easily pumped from ground, job oppertunities, used for planes, trains, cars
- clearcutting?
- the act of removal of all trees in an area
- reforestation
- wood is renewable
- drawbacks on clear-cutting
- reduce air quality, climate change,
- benefits of shaft mining
- less waste produced.
- drawbacks of shaft mining
- more dangerous, potential tunnel collapsing. lung disease, more expensive.
- effects of mining on enviroment
- harm, habitats, can make soil and water acidic
- drawbacks of agriculture
- excessive water use, greenhouse gases, high land use, soil contamination.
- effective harvesting method
- safer for workers, larger trees, little planning
- drawbacks of nuclear energy
- dangerous to health, lethal for thousands of years
- drawbacks of geothermal energy
- difficult to transport to urban areas, decline in geothermal stream supply, depleting energy source
- benefits of landfills
- garbage is covered with a layer of soil, prevents breeding of insects
