Managing Canadas Resources Flashcards
What is a natural resource?
a natural formed material or substance which can be used itself or sold to earn money
eg. fish, water, minerals(gold), trees, oil, has, wheat
What is a renewable resource?
A resource that can replenish (grow back) within 30 years
eg. trees, fish, soil
What is a non renewable resource?
a resource that can only be used once
eg. oil, gas, minerals
What is a flow resource?
it is a resource that renews its self while it is being used
eg. sun, wind, water
What is a sustainable development?
Using the resources we have now but making sure we will have enough resources for the future.
What resources will we run out of in the future?
gas
non renewable resources
What renewable resource are we ruining?
fish in particular cod
trees
water
What is an example of a resource that we use in a sustainable way?
solar energy
What is included in the linear system?
1) extraction
2)production
3)distribution
4) consumption
5)disposal
=materials economy
What is an ecological footprint?
a statistic(number) used to measure how people impact their environment
How is ecological footprint calculated?
natural resources used+garbage made+land needed to make & distribute all the stuff you use
- expressed in hectares
What is the average North American EF and why are they so high?
- 9.5 hectares
- they drive a lot (uses oil, makes wider roads)
- haves lots of clothes and buy more then what they need (grow cotton, use energy for machines to make clothes; use oil for transportation
- eat more then what we need( need 2000 cals but consumes 3400cals)(need more food, more transportation)
What are the 6 footprints?
Build-up footprints fish footprints forest footprints grazing footprints crop footprints carbon footprints (highest type of footprint)
Do Middle Eastern countries have more carbon?
yes
What is the highest footprint in Ontario?
carbon footprint
Why is carbon the highest footprint?
- most countries are industrial
- there is a lot of use of oil, gas, coal(fossil fuels) for transportation, energy and factories
What is the range of the highest footprints?
5.7 hectares to 9.7 hectares
facts about worlds
- world average=1.6 worlds
- if we lived like Australians we -would need 5.4 worlds
- if we lived like the indians we would only nee 0.7 of a world
Why do indians have small footprints?
- don’t have much money
- don’t drive(bike, walk, scoot, train, bus)
- eat simple local foods and sometimes don’t have enough
Cartogram definition
a map distortion showing data or concepts visually
What are the different levels of the solid waste management hierarchy?
reduce- lowering the amount of waste produced
reuse- using materials repeatedly
recycle- using materials to make new products
recovery- recovering energy from waste
landfill- safe disposal of waste to landfill
Least desirable-landfill
throw garbage into lanfill
Produces:
1) methane- a ghg that contributes to global warming
2) leachate- water decomposing items that may carry toxic dissolved materials
Better: Landfill with energy recovery
- methane gases release as items in dump decompose
- if captured it can be burned as fuel to create electricity
Benefits: - free energy
- delays methane getting to atmosphere
Even better: Recycle and Compost
- less land used for garbage
Why is it not enough? - not everything is recyclable(multiple types of materials in 1 item)
- not everyone participates
- uses large amount of energy( transport, incineration, moulding)
- too much supply of resin pallets
- oil companies make the same product so no need to buy recycled material
Best: reduce/reuse
source reduction: don’t produce waste in the first place
- old days: nothing pre-packaged
- today: bulk buying, farmers markets
only occurs when public demands it
Impacts of public demand
a) businesses comply so people buy there product
b) government makes laws in hopes of gaining votes
Information of naturel resources in the US
US is 5% of the worlds population but uses 30% of the worlds resources. If everyone lived like the US we would need 5 planets.
how are our products made?
naturel resources go in with toxic chemicals and energy to make products with toxins in them. toxins in toxins out.
How much pollution is in the US each year?
The US admits to having 4 billion LBs of pollution each year polluting air, water, and land
What is the golden arrow?
the golden arrow of consumption
What is planned obsolescence and what is perceived obsolescence?
planned obsolescence: designed for the dump such as light bulbs
perceived obsolescence:
out of fashion such as thin heels and thick heels
What are adds doing to us?
they are telling us to be happy we must buy new things
How much garbage do humans make per day?
twice the amount of garbage from 30 years ago
What type of toxin is made from burning toxic chamicals?
dioxins which is a very powerful toxin
Why is this system seen as a system in crisis?
It is seen as a system in crisis as it is in no way sustainable for our environment. We use too many natural resources producing pollution, consuming/buying way more and wasting out resources.
Why isn’t recycling enough to solve our environmental problems?
Its not enough because we still have so much garbage in the end that needs to be handled in a way that we don’t have the answers to yet
Why has our nations happiness level decreased even though we have more stuff than even before?
It decreased caused by our consumption levels as because of this we have less time to see and spend time with friends and family. As well as do things we enjoy such as sports, hobbies ect.
Explain the “work-watch-spead” treadmill
Everyday people go to work, come home exhausted, watch tv, see things we want and need to be happy, go shopping to make ourselves feel better, go back to work to pay for the things that we bought and so on.
What does “sustainable” mean in terms of our ways of life, economic systems, and our impact on the environment?
being sustainable is being more green for our earth so that the resources we have know will last for the future. Use recycling, be zero waste, don’t buy fast fashion. All of that creates a sustainable environment. Not for lour economy because we will have to buy less and get our clothes from sustainable stores such as thrift store.
What can the government do to fix this system?
The government can advertise to the public to decrease the amount of garbage being produced and put laws in regarding how to fix the waste/overuse of naturel resources.
What can corporations do to fix this system?
They can make the adds feel more mutual like if you want it get it but its not needed to help you feel not as bad.
What can we do to fix this system?
We can advertise what the system is creating and how it is making a non sustainable living environment. We can also do little things like recycle and go waste free.
What is the history of east coast fishery?
- fishing off the coast of Newfoundland began in the 1500s
- ships came from Great Britain, France, Spain, Portugal
- fish were dried or salted and sent to USA or the Caribbean
What are the 2 reasons as to why there is a lot of fish in the grand banks of Newfoundland?
1) cold Labrador currents meets warm Gulf stream currents (churns up ingredients that plankton need to grow)
2) wide swallow continental shelf (sunlight reaches bottom and grows plankton which fish eats)
Canadas fishing limit
Canada controls the water (above and below) 370km from shore. (200 nautical miles)
Inshore fishery
- stays close to shore
- returns home every night
- gets 10% of total catch
- small boats with 1-6 crew members
- season work
- fish processed onshore
Offshore fishery
- fish at the limits of Canadian shore
- stays onboard up to 14 nights
- get 90% of the catch
- big boats with 6-12 crew members
- 4 season work
- fish processed onboard ship
Reasons for the Collapse of Cod
- over fishing
- improved fishing technology (post WW11) 1950s
- destructive fishing practices: dragnets capture everything
- changes in naturel conditions: change in current, increase in seals
- uncontrolled forgien fishing (until 1977)
Crisis in the east coast fishery
- 1980s notice fewer and smaller fish caught
- 1992 government stops all commercial fishing
- hope the fish will come back in 5-7 years but have not
moratorium=ban
In Oregon farm country, what is twine recycled to?
bumpers and truck liners
What are flowerpots recycled into?
more flower trays and pots
What is “down-cycling”? How is it different from recycling?
Down-cycling is when you turn one product into an inferior product but it can only be recycled one. Recycling can be recycled thousands of times.
California- Inference. carpet company. Where do they get their energy from?
they get their energy from methane from local landfills
India. What are some alternatives in the video to using thin shopping bags?
- locally grown jute
-
Anita Ahuja from Conserve India. How is her company part of the solution to the problem of plastic shopping bags?
- She collects the plastic bags that are going to be put into landfills and hand washes them. After that she turns them into things such as jewelry, bags and much more that are sold around thew world.
