- What do we eat?
- What do other cultures eat?
- Are we using our food resources effectively?
- What changes could we make to do better?
3Do we have enough for all?
- Can the world support the population that is
skyrocketing? Can we feed these folks?
4Our global grocery
- Despite the fact that we have innumerable edibles
on our planet, we exist on - One dozen seeds/grains
- 20 fruits/vegetables
- 6 mammals
- 2 fowl
- A few fish and marine life
5Our global grocery
- Beef

10Major Crops of the World
11Some staggering numbers
- 1,600 metric tons grown each year
- Staples for 5 billion people
- 60 calories consumed by people directly
12What about special climates?
- Sometimes these crops cannot be grown in the
areas due to climate limits. - As a result some folks have adapted to eating
what they can grow.
13Cool, moist, high altitude climes
- Potatoes, barley, oats, rye
14Warm, wet climes
- Cassava, sweet potatoes, roots and tubers
15Drought options
16Fruits and Vegetables
- High levels of vitamins
- Minerals
- Fiber
- Complex carbohydrates
17Now for the Decadent foodstuffs
- Meat
- Milk
- Seafood
- Do we need it?
- No.
- Do we want it and like it?
- Yes.
18The Stats
- North America, Japan and Europe (20 of the
worlds population) consume 80 of the worlds
meat. - The 80 raise 60 of the 3 billion ruminants and
6 billion poultry but only consume 20 of the
animals products. - HMMMMMsomethings wrong here?
19HMMMMMsomethings wrong here?
20Heres the most amazing fact
- 90 percent of US grain goes to feeding dairy and
beef cattle, hogs, poultry, and other animals.
21Ponder that for a moment.
Where should the Life giving grain go?
22Consider the numbers
- 16kg of soybeans gets turned into 1kg edible beef
(15kg wasted as heat.review?) - If you ate it directly you would get 21 times
more calories and 8 times more protein as well as
a healthier colon and heart. - Hogs 2 times as efficient as beef
- Poultry 4 times as efficient
23Vegetarianism
- Could you make an argument that its better for
- Your health
- Human rights
- The environment
- Global change
- An animal rights too?
- Might be something to check into.
- This is why I hunt.
24Arguments against meat
- Tax the meat!
- Meat consumption in the US
- Go veg
- Scary facts from the union for concerned
scientists
25Ahhhhh..and seafood.
- 94 million metric tons of seafood are consumed by
humans - Important protein source for some countries
26So whats the problem with fish?
- Over harvesting and habitat destruction
27Some Scary stats
- Since 1989 14 of 17 major marine fisheries have
taken a plunge in population - UN 70 of edible seafood is declining and in
need of conservation efforts - 1 in 4 animals caught is an unwanted catch.
- (birds, mammals, reptiles, other fish)
28WHY????
- Pressures of a growing population
- Better fishing technology
- Global warming and habitat damage
- Exotics
29- After decades of growth, the reported global wild
fish catch peaked in 2000 at 96 million tons and
fell to 90 million tons in 2003, the last year
for which worldwide data are available. The
catch per person dropped from an average of 17
kilograms in the late 1980s to 14 kilograms in
2003the lowest figure since 1965.
30Annual fish catch (millions of tonnes) North
America
31Annual fish, mollusc and crustacean catch
(milllion tonnes) by region
32Annual fish, mollusc and crustacean catch per
capita (kg) by region
33Annual aquaculture production (million tonnes) by
region
34Some cool Overharvesting links

35Types of fishing methods
- Links to types of fishing
- Pics of types of fishing
36How to save our oceans
- Is it that complex of an issue?
- EAT fish that you know has been farmed in a
sustainable way. - Convince others to save the fish while there is
still time.
37SO what does this all mean to you?
38What role does food play for you in your life?
- Culture
- Survival
- Social norms
