FOOD RESOURCES & WORLD HUNGER
Important and complex! Strongly linked to the topic of “population growth”.
WHAT IS THE PROBLEM?
More than half of the world’s people spend much of their time and income … trying to
get enough food to keep themselves and their children alive!
In contrast some people in a few affluent countries are actually troubled by an
abundance of food! They may spend time and income trying to get rid of the effects of
excess food!
Name some:
- diets - diet foods
- fat busting activities - fat-busting equipment
- eating disorders
40% of Canadians (60% of Americans) are obese! People in MDCs are killing
themselves with food/lifestyle-related diseases such as heart disease, cancer, and
diabetes.
Meanwhile back in many LDCs many people are hungry, and there are more mouths
to feed each day!
(Some quotes …) But basically, can we grow and distribute enough food to stay ahead
of population growth???
FIVE SIGNS OF TROUBLE
1) Food production has been increasing, but the rate of increase has been
declining! We seem to be losing the race against population growth!
2) Many regions are showing a degraded agricultural potential (soil erosion;
desertification).
3) Although the percentage of malnourished people has declined … there are now
more hungry people than ever! (At least 1 of every 10 people is too poor to buy
enough food … or has insufficient land to grow it.)
4) 30 to 40 years ago, most countries were completely self sufficient in food and
could export. Today all but 7 countries are barely self sufficient or are net
importers of food. (The regular net food exporters are: the U.S., Canada,
Australia, New Zealand, Western Europe, Argentina, and Thailand.)
(“What will happen as China gets hungrier?” CIA)
5) Hunger is not restricted to LDCs. More than 30 million North Americans are too
poor to buy adequate food, although they may live in very wealthy cities.

OneClass has been such a huge help in my studies at UofT especially since I am a transfer student. OneClass is the study buddy I never had before and definitely gives me the extra push to get from a B to an A!

Balancing social life With academics can be difficult, that is why I'm so glad that OneClass is out there where I can find the top notes for all of my classes. Now I can be the all-star student I want to be.
