Advantages
Disadvantages

5. Industrialized Meat Production
CAFOs (Confined Animal Feeding Operations)
Keeping large number of animals in a small space.

6. Industrialized Meat Production
Corn-based diet
Cows can gain more weight in less time
Requires less space

7. Advantages of CAFOs
Increased Meat production More profit
Less land use protection of biodiversity
Reduced overgrazing
Reduced soil erosion

8. Advantages of CAFOs
Increased meat production increased meat consumption

9. Disadvantages of CAFOs
Contribute to climate change
CAFO cattle produce twice as much methane as grass-fed cattle

10. Disadvantages of CAFOs
Hormones given to animals
Hormones stimulate growth and milk production
Used for beef cows and dairy cows
Raises human health concerns
How much is in our food products?
How much do we absorb?

11. Disadvantages of CAFOs
Antibiotics given as preventatives
Increase in antibiotic resistant bacteria

12. Disadvantages of CAFOs
Zoonotic Pathogens crossing over to humans
Mad cow disease
H1N1 Flu (swine flu)
Avian Flu

13. CAFOs Disadvantages CAFOs contribute to water pollution.
Runoff carries nitrates and bacteria from manure into nearby lakes and streams.
This can trickle down into ground water.
