Our
Food Supply
Subject Area
This activity
has been designed to work with the Food and Nutrition Science
NZD 3G1 curriculum. It fits with Unit 1: Food Choices (core unit)
as outlined in the Food and Nutrition Sciences Curriculum Guideline
for the Senior Division, August 1988. This material has been assigned
to explore objective D on page 61.
Learning
Outcomes
Teaching,
learning and evaluation will focus on the students ability
to:
- Investigate
and analyze the sources of our food supply;
- Research
the meaning of terms used to describe the food supply;
- Discuss
critically the implications of imports on both importing and
exporting countries;
- Develop
and justify a policy for the selection of food.
Classroom
Development
- Students
use grocery flyer ads to identify the variety of products imported
to Canada and their countries of origin
- Note
the source of the products on a world map. Share findings and
record them on the worksheet provided.
- Students
complete worksheet questions to explore implications of our
imported food products.
Timing
Allow one
70 min period for students to complete this activity. Additional
time would be required for extension activities.
Resources
Students
will need a selection of grocery flyer ads and a large world map
which could be an outline on chalkboard, overhead transparency,
or chart paper. Food product names/pictures could be pinned/taped
to world map. Yarn could be used to join these product origin
locations to the location of the school.

Answer
the following questions using your knowledge of imported foods.
- Why
are products such as oranges and pineapples imported?
- Name
3 other products imported for the same reason.
- Why
do Canadians buy imported food?
- List
all the resources that are used when foods are transported.
- What
impact does this have on the environment?
- If countries
concentrate their agricultural efforts on cash crops to be exported
there is less land available for what other type of crop?
- How
can some food products be produced so cheaply in countries outside
North America ?
- What
will happen if consumers continually choose imported foods instead
of locally grown foods (For example Florida oranges instead
of Ontario apples.)?
- What
are the benefits of selecting locally grown foods?
Answer
Sheet
- Products
like oranges and pineapples cannot be grown in Canadas
temperate climate.
- Any tropical
foods.
- Foods
are obtained for variety, because they are not available fresh
in winter, and they are sometimes cheaper.
- Fossil
fuels, transportation vehicles, highways and rail corridors.
- Burning
fossil fuels causes air pollution and contributes to global
warming.
- Foods
required for local consumption are often not grown, or are grown
at a premium price. For example, in Brazil, sugar cane is grown
in large quantities for export but many Brazilians do not have
enough food.
- Wages
for workers and profits for farmers are much lower in other
parts of the world. Also, many pesticides which are considered
too dangerous for use in Canada are used in these countries.
- If agriculture
is not profitable farmers will lose their farms and we will
become dependent on imported food, and the changes in foreign
political policy.
- Locally
grown food is fresher, more nutritious and cheaper in season.
In this country, agricultural chemicals are regulated and minimum
wages for workers are guaranteed, so food produced in our country
is safer to eat and more socially beneficial.
