Production: Few countries export food (Canada, US, etc.) Number
of countries importing food has risen to over 100. In general, good
production has increased; however, this has only happened in
countries where producing food is easy.

Slide 5
Distribution: the earth can support its population, but some
people have too much food, while others have too little. People who
need food cannot afford it Landowners produce cash-crops (Tobacco,
Poppies, etc.) rather than food Drought High population growth
Hunger cycle
Slide 6
Slide 7
Desertification: Deserts (Sahara, Kalahari, etc.) are advancing
several km per year. Vast tracks of land are becoming drier than
average Rapid population growth puts pressure on the land Economic
priorities such infrastructure development take precedent over land
conservation.

Deforestation: Wood for fuel Soil erosion Overgrazing: Soil
exposed Water runs off Over-cropping: Cultivation exposes soil

Slide 11
1) Create a T-Chart outlining 6 Causes of famine in Bangladesh
and 3 Effects. 2) List the 7 Points of Chinas food production
drive. 3) According to this article, name 3 differences between
China and Bangladesh (Hint: think government, religion, resources,
etc.).
Slide 12
Slide 13
Clearing Tropical rainforests Can cause environmental problems
Reclaiming Grazing Land Need irrigation, which is expensive May
change culture/tradition in some societies May lower ground water
levels
Slide 14
Slide 15
The Green Revolution: increased crop production through more
intensive use of land. Improvements made in: Higher yield plants
Fertilizers Water control Insecticides Mechanization Plant &
animal breeding Transportation/storage/marketing Problems:
Expensive Distorting gene pool of plants.
Slide 16
Slide 17
Food from the Ocean: Problem: over-fishing Aqua-culture: Fish
farms Fish hatcheries Problems: Not efficient High cost Water
pollution/disease Synthetic Food Production (Pills) Problems:
Unknown? Cost
Slide 18
Slide 19
New Food Crops: 20,000 types of food plants exist People only
eat approx. 100 types 22 of the types feed the majority of the
worlds population. Problem: Difficult to change peoples habits.
Waste: reduce the amount of food waste
