Natural Resources Around the World: Use and Sustainability: Unit Review

Iron ore: non-renewable. Tides: flow. Spruce trees: renewable.

Fossil fuels form in sedimentary rock, and the Interior Plains sit on thick sedimentary rock layers.

If it is used faster than it can be replaced, for example overfishing.

Any three: lumber (houses, furniture), paper and cardboard, fuel (firewood, pellets), recreation in forests.

A want.

Gravel is heavy and costly to transport, and cities need a lot of it.

An underground mine (shafts and tunnels), because it's too deep for an open pit.

Any two: distance, transportation, terrain/climate, depth, technology, price/demand.

It can damage the sea floor and catch lots of bycatch.

Its mountains and heavy rain and snow create many steep, full rivers.

Radioactive waste must be stored safely for a very long time (also: very costly to build).

The wind doesn't always blow.

The forest is not replaced, habitat and carbon storage are lost, many local people lose out, and it can't continue for future generations.

The Government of Canada announced a moratorium after the stock collapsed.

People with few choices may need to clear forest, cut trees for fuel or overfish to survive today.

Any two: acidic lakes where fish can't survive, damaged forests and plants, harmed soil.

Long-term.

It shrank greatly after its rivers were used to irrigate cotton, leaving dry, salty land.

Residents may focus on jobs and the local economy; the environmental group may focus on pollution and habitat. Their needs and values differ.

Governments must consult Indigenous peoples when a decision could affect their rights.

False. Communities and people within them hold different views.

The seafood comes from a fishery certified as sustainable by the Marine Stewardship Council.

Making a product seem better for the environment than it is, without independent proof.

Reducing means the item is never made, so no resources or energy are used.

Examples: UNEP; Nature Conservancy of Canada (or Friends of the Earth International, Rainforest Alliance, The Nature Conservancy); Indigenous Guardians or the Haida Gwaii Watchmen.

Results.

A limit on how much fish can be caught.

A flow map.

Stack them, turn them on and off, and compare them to find patterns and interrelationships.

It can spread pests like the emerald ash borer.

Example: "What are the environmental, economic and social impacts of overfishing off West Africa, and how could they be reduced?"

Environmental, economic, political, social.

To check for bias and get a fuller, fairer picture.

Example: "For two weeks, I'll keep my showers under 5 minutes using a timer and record each one on a chart."

Examples: a poster, a short class talk, a letter to a council member, starting a swap or repair event.

To see what worked and what to change.
