Unit 4-resourses Flashcards
What are the 5 major resource industries in Canada?
Energy: Canada ranks in the top 5 in the world for production of natural gas and electricity.
Farming
Fishing
Forestry: nearly 10% of the world’s forests are found in Canada
Mining
Water: Canada holds 20% of the world’s fresh water
What are renewable resources?
A resource that can be replenished within a human lifetime.
What is a Non-renewable resource?
A resource that cannot be replenished within a human lifetime.
What is sustainable development?
Managing natural resources so that future generations will be able to use them.
How do we over use trees and how can we be more sustainable?
Overuse: People over harvest them from their own needs (wood, making furniture etc..) Forest fires. A lot of forest fires happen which kill a lot of trees daily Cut down trees and don't replant them Harming younger trees Sustainable: Replant Be caution when you are in a forest area Recycle Replacement (iPad instead of paper) Use the whole tree
How do we over use fish and how can we be more sustainable?
Overuse:
Population of some fish species are going down due to over harvesting.
They have new technology where it’s easier to get fish which can also result in over harvesting
We waste perfect rural land to store fish
Pollution
Waste water
Drouts
Oil spills
Sustainable:
Harvest all different types of fish so your not only getting the same type of fish that could make them endangered
Have a harvesting limit so people know when to stop
Don’t pollute (decrease motor use)
Through the fish back in the water after fishing
Try to use the whole fish
How do we over use water and how can we be more sustainable?
Over use: Pollution Waste water Drouts Oil spills Sustainable: Don't pollute Don't litter Use water wisely
How do we over use energy and how can we be more sustainable?
Overuse: Wasting it Wasting land for wind turbines Sustainable: Turn off light when not using Be aware of the footprint our energy will take up Alternative energy sources (wind) But energy efficient appliances Develop laws to use energy more efficiently
How do we over use soil (agriculture) and how can we be more sustainable?
Overuse: They use a lot of land (11 billion hectares) Deforestation Construction and development Climate change Excessive rain Pollution Salt gets into soil (kill trees) Over use. Sustainable: Put fertilizer Put compost Do organic farming (non Gmn foods)
List 5 major types of farms in Canada?
Wheat farming Cattle raising Dairy farming Tender fruit farming Vegetable farming
In the past how many Canadiens live in rural areas?
82%
Now how many Canadiens are farmers?
3%
What is extensive farming?
Farm size: large
Amount of labour: a lot of machinery and few workers
Technology based
What is intensive farming?
Farm size: small
Amount of labour: highly specialized labour and equipment
How can untreated manure pollute the environment?
Rain can wash it into rivers, streams, and wells, polluting humans drinking water.
What are the 3 methods of cutting forest? Advantages and disadvantages.
Clear cutting: cutting down whole areas. Advantages: easy, quick and cheap disadvantages: new trees won’t grow, tourism suffers (eyesore)
Shelterwood logging: leaves small pockets of trees. Advantages: reproduction is more certain, higher quality growth, looks better and better use of site. Disadvantage: damages trees, soil compaction, tree loss and soil erosion
Selective cutting: pick only certain trees to cut down. People who make furniture do this
What are the 3 main fisherys in Canada?
Atlantic: accounts for 78.5% of Canada’s total fish catch. Made up of inshore and offshore fishing.
Pacific: accounts for 18.5% of Canada’s total. Most important catch is salmon.
Freshwater: occurs in the heat lakes, lake Winnipeg and Great Salve Lake. Accounts for 3% of Canada’s total fish catch.
What are problems effecting the fishing industry?
- Large commercial boats
2. Large nets used for trawling
