Q

how does food waste happen in the retail/ buisness phase?

A

Food loss happens at this stage due to:
• Shrink: when buyers order to much and suddenly “shrink” their order from producers leaving them without a buyer
• Caused by: Buyers over order-don’t want to be shorted or over projected amounts needed

• Overstocking: abundance appearance increases long term sales but causes food waste and purchasing too much of unpopular foods
• Consumer expectation of cosmetic perfection: fruits, vegetables and other foods
• Oversized packages
• Planning Issues: Availability of prepared food until
closing (ex: deli chickens)
• Expiration and Best before dates
• Damaged goods (dented cans etc.)
• Under-staffing

Q

WHY IS DISPOSING OF ORGANICS IN A LANDFILL BAD?

A

1) They do not break down properly! They need air to break down, without air they create leachate (garbage juice) and release methane into the atmosphere. Every ton of food waste gives off 1.15 tonnes of methane.
2) Building a new landfill is VERY expensive

Q

WHAT CAN WE DO WITH OUR ORGANICS?

A

1) Home Compost
2) Use the GREEN CART

25
Q

What is backyard composting?

A

Using a compost bin, dispose of
organics in your backyard

26
Q

what is Trench Composting

A

Burying organic waste under several inches of soil and letting the foil food web do all the work!

27
Q

what are two ways to do indoor composting?

A

Vermicompost + Bokashi buckets

28
Q

What is climate change?

A

Describes a change in the average conditions
(temperature and rainfall) in a region over a long period of time.

29
Q

What is the primary cause of climate change?

A

Greenhouse gases.

30
Q

How is carbon released into the atmosphere?

A

Burning of fossil fuels releases carbon dioxide in the atmosphere.

31
Q

What other activities have humans participated in that limit the planet’s ability to reabsorb greenhouse gases?

A

Deforestation

32
Q

Mitigate (define):

A

Making something bad less severe. For example,
reduce greenhouse gas emissions, or increase carbon sinks.

33
Q

Adapt (define):

A

Taking steps to reduce our vulnerability and to increase our preparedness when facing the impacts of climate change.

34
Q

Who is the contributing the most to climate change?

A

Wealthy people are responsible for more emissions.

35
Q

Who is most at risk to the effects of climate change?

A

Poor people

36
Q

How will climate change impact food prices?

A

Reduced food production means increased prices.

37
Q

What are examples of extreme weather events that will impact our ability to grow food? (the example for New Brunswick applies to all of Canada).

A

Heat waves, cold snaps, droughts, snow storms, hail

38
Q

What are extreme weather events we have recently experienced in the prairie provinces (SK, Alberta, and Manitoba?)

A

snow storms, change of temperature, extreme heat, extreme cold

39
Q

Why are rainfall and temperatures important to agricultural production?

A

Crops need ideal conditions to grow. Too much rain or too little rain can cause crop failure.

40
Q

How does agricultural production contribute to climate change?

A

By increasing greenhouse gas emissions.

41
Q

List examples of practices and methods that focus on sustainable agriculture?

A

zero tillage, conservation practices, rotating crops, enhanced natural resources,

42
Q

A

It captures 25% of all CO2 emissions and is one of the world’s largest carbon sinks.

43
Q

What impact does ocean acidification have?

A

Can degrade coral and shell- fish. Coral is important for maintaining balance in ocean ecosystems.

44
Q

How have rising global temperatures impacted fish species?

A

Destroys habitats and changes migratory patterns. This can make it difficult for certain species to reproduce.

45
Q

.How have colonialism and climate change impacted Indigenous wild foodways?

A

Deprived Indigenous Peoples of food.

46
Q

.How does the energy used to transport food contribute to climate change?

A

Creates greenhouse gases that trap the heat from the sun.

47
Q

What is meant by the concept: “Shorten Your Fooodchain”?

A

Buy locally, so your food doesn’t have to travel as much.

48
Q

What are the benefits of buying locally?

A

Support our local economy, creating local jobs. Less habitat loss, less pollution and less food waste.
