No regulations

22
Q

How was the Canadian inshore and offshore fishing industry involved in the destruction of the East Coast Cod Fishery?

A

Unsustainable fishing practices
Focused on economic gain rather than sustainability

23
Q

How was the marine scientists involved in the destruction of the East Coast Cod Fishery?

A

Underestimated risks

24
Q

How was the government officials involved in the destruction of the East Coast Cod Fishery?

A

Delayed regulations
Relied on fishing for income
Didn’t listen to warnings from scientists

25
Q

What is the tragedy of the commons?

A

When people are selfish and deplete a common resource, not leaving enough for future generations

26
Q

What are the commons?

A

Public area everyone has access to

27
Q

What is sustainability?

A

Meeting the needs of the present without limiting the ability of people to survive

A

Fish caught near ocean floor

Examples:
Cod
Halibut
Haddock

30

33
Q

How was Atlantic Canada affected by the closure of the cod fishery?

A

Change in the economy and unemployed around 35,400 people

34
Q

What is bottom trawling?

A

When nets are dragged along the ocean floor by a boat through water which catch more fish than needed and destroy ocean habitats.

35
Q

What is by catch?

A

When unwanted creatures are caught during fishing

36
Q

What are ghost nets?

A

Nets that have been abandoned in the ocean and are invisible

37
Q

What is energy?

A

The capacity for a physical system to work

38
Q

What are the measurements of energy?

A

Joule (J)
Gigajoule (GJ) = 1 billion Joules
Petajoule (PJ) = 1 million Gigajoules

39
Q

Why is Canada one of the world’s largest users of energy?

A

Northern climate
Large land mass
Industries
Cheap energy

40
Q

What is conventional energy?

A

Non-renewable energy such as oil, natural gas, and coal

41
Q

What is alternative energy?

A

Renewable energy such as wind, solar, and tidal

42
Q

How does wind energy work, pros and cons, and how does Canada use it?

A

How it works:
Wind turns generator that uses kinetic energy to make energy

Pros:
Free source, environmentally friendly

Cons:
Expensive set up, kills birds, inconsistent

Canada use:
Canada is committed to increase this supply of clean, renewable energy

43
Q

How does solar energy work, pros and cons, and how does Canada use it?

A

How it works:
Dark panels absorb heat from sun, heat is transferred to fluids, high pressure steam spins turbine

Pros:
Free source, environmentally friendly, unlimited

Cons:
Not efficient, expensive set-up

Canada use:
Colville Lake in Northwest Territories successfully tested a solar panel system that allowed the community to run entirely on the sun’s energy

44
Q

How does tidal energy work, pros and cons, and how does Canada use it?

A

How it works: When a tide reaches its highest level, gates of a dam like structure close and holds water. When the level drops, it runs through turbines

Pros: Free source, unlimited

Cons: Only 25 locations, eyesore, safety issues

Canada use: Canada ranks 4th in the world in tidal power capacity with 40mw

45
Q

How does hydro energy work, pros and cons, and how does Canada use it?

A

How it works: Falling water spins turbines within a dam

Pros: Renewable, environmentally friendly

Cons: Flooding impacts, expensive set-up

Canada use: Canada is the third largest producer of hydroelectricity in the world

46
Q

How does nuclear energy work, pros and cons, and how does Canada use it?

A

How it works: Uranium’s U-235 atom’s nucleus is hit by a neutron which releases energy that’s absorbed

Pros: Lots of source

Cons: Safety concerns, expensive setup

Canada use:

47
Q

How does geothermal energy work, pros and cons, and how does Canada use it?

A

How it works: Wells are drilled into the earth where hot water and steam are taken out, steam is used to spin a turbine

Pros: Environmentally friendly, unlimited

Cons: Expensive-set up, few locations

Canada use: Geothermal potential energy in Canada is estimated to over 5,000 mw

48
Q

How does biomass energy work, pros and cons, and how does Canada use it?

A

How it works: Biomass is burned and heats boilers which generates steam and spins turbines

Pros: Gets rid of waste, environmentally friendly

Cons: Better uses for natural products

Canada use: Biomass accounted for 2% of Canada’s electricity production in 2016

49
Q

How does fracking energy work, pros and cons, and how does Canada use it?

A

How it works: High pressure water is directed at rock within the earth to release gas

Pros: Financial benefits, material access, job opportunities

Cons: Damages environment, risk of earthquakes, pollution

Canada use: Used in more than 180,000 wells in Alberta

50
Q

What are gill nets?

A

Passing fish get caught in a net
