Chapter 4,5,&6

• Total Shock: all parts of the natural environment including energy, living organisms, and non-living materials
• Eg of total shock: water, sunlight, and trees
• Resource: anything that can be used to produce goods and services
• Examples of resources: raw materials, workers, money, and land
• natural resources: things found in the total shock that people found useful.
• Renewable resources: resources that can be regenerated if used carefully
• Non-renewable: resources that are limited and cannot be replaced once they are used up
• Flow: resources that are replaced by natural actions and must be used when and where they occur or be lost
• other resources: resource that do not fit into any of the categories
• water diversion: processes that reduce the amount of waste that ends up going to landfills. Process includes reducing reuse and recycling
• conservation: the wise use of resources
• Mining the resource: exploiting a renewable resource in an unsustainable way
• Sustained Yield Management: the process of managing a renewable resource to ensure that the amount harvested does not cause long-term depletion of the resource.
• absolute measure: a quantity of something using simple units, such as kilometers, dollars, or several people.
• Relative measure: a quantity of something compared to the quantity of something else, using units such as percentages and ratios
• old growth forest: a forest that has never been logged
• Aquaculture: fish farming
• Continental shelf: the part of the ocean that is net to continents and is typically less than 200 meters deep.
• banks: shallow parts of the continental shelf that are good for fishing
• Inshore fishery: commercial fishing carried out close to shore in small, independently owned boats
• Offshore Fishery: commercial fishing carried out further from shore in larger company-owned boats
• Precipitation: water from the atmosphere that falls to earth, including rain, snow, hail, and sleet
• Stores: places in the world where water is stored
• Flows: mechanisms by which stores move from on reserve to another.
• groundwater: water held underground in tiny spaces in the soil or some types of rocks
• Aridity Index: a value used to show water availability. It combines measures of supply and natural demand.
• Potential evapotranspiration: The natural demand for water in a particular enviroment
• extraction: the process of taking water from a store to be used. It is returned eventually
• Consumption: the process of taking water from a store to be used and not to be returned
• Drainage basin: the area of land in which all of the water flows (drains) to the same body of water
• Bulk water exports: any water exports in quantities larger than 20 litre containers
• Blue planet: Earth
• Earths waters nearly cover 75% of the surface
• Who relies on water the most?

  Farmers and first nations
• Water availability is due to?

  Precipitation
• What is water used for?

  demand by natural demands and humans
• Water Deficit: more water goes out that comes in
• Water sources: ice sheets, glaciers, groundwater, lakes and rivers
• Three major uses of water: Agriculture (irrigation), Industry, and Domestic (drinking, cooking, cleaning)
• Canadians have vast amounts of water and can afford to build and maintain water plants
