The Role of Food Animal Production
The Connection Between Livestock and Crops
n 
Only 1/32 of the earth’s surface is suitable for food production
n 
Meat production is an inefficient use of resources: grain, land,
water
n 
Meat production accounts for …
-  70% of all agricultural land
-  30% of the planet’s land surface
-  40% of the world’s grain is grown for livestock feed
Sources: American Farmland Trust; Worldwatch; National Corn Growers Association; FAO.

The Connection Between Livestock and Crops
n 
7% of global water use is to grow feed grains for livestock
n 
70% of herbicide and 37% of insecticide use in US agriculture can be
attributed to the livestock industry in the form of corn and soy feed
n 
About half of the corn grown in the US is used as animal feed vs.
less than 1% for direct human consumption, such as sweet corn (i.e.,
corn on the cob)
Sources: American Farmland Trust; Worldwatch; National Corn Growers Association; FAO.

Increasing Grain Consumption
“… steadily rising consumption due to population growth and
expanding livestock sectors will again outstrip production”

What Is Industrial Food Animal Production?
n 
Vertical integration
- 
One corporation controls nearly
every aspect of production and
processing
n 
Animals grown in confined animal
feeding operations (CAFOs)
n 
Animal feed and conditions strictly
controlled by corporation, not by the
“grower”
n 
Contracts often restrict rights of
“growers”
n 
Grower has to deal with waste and
losses
8
The Size of the System
n 
Livestock outnumber humans in the US (5:1)
- 
5 tons of animal waste for each person
n 
In 2002 ...
-  10 billion animals in the US were slaughtered for food
-  50 billion worldwide
  93% chickens (46 billion)
n 
In the US
-  35 million cattle
- 
- 
100 million hogs
More than 95% chickens and turkeys
  1 million broilers killed each hour
9
CAFO Effects on Public Health
n 
Concentrated, high-speed meat production leads to greater risk
from foodborne pathogens, some of them newly emerging
n 
Excessive antibiotic use in animal agriculture may create resistant
strains of microbes in humans
n 
Persistent organic pollutants (dioxins, furans, polychlorinated
bromides) enter the food chain through the diets of food animals
n 
Communities are usually not involved in decisions to build or expand
CAFOs
n 
Health threats from CAFOs magnified in those most closely and
regularly exposed
n 
Workers, their families, and community members have higher than
average rates of injuries and various illnesses
10
Livestock and Climate Change
n 
Livestock are responsible for 18% of greenhouse gas (GHG) emissions
(FAO, Livestock’s Long Shadow, 2006)
- 
Greater contribution than transportation
n 
37% of emissions of methane
-  More than 20-times the global warming potential of CO2
n 
65% of emissions of nitrous oxide
-  286-times the global warming potential of CO2
- 
- 
Stays in the atmosphere for 114 years
Nitrogen-based fertilizers are a top source
  51% of US nitrogen is used for fertilizers for animal feed/
pasture

Agricultural Trends to 2035
n 
From agricultural expert Dennis Keeney*
- 
- 
- 
- 
Global climate disruption accelerates
Grain yields continue to increase, but more slowly
New markets develop, particularly for biofuels
More pressure worldwide on food availability, cost, because of
of the following:
  Rising population
  Increasing living standards
  Droughts and floods in grain-producing regions
 
Non-food uses (biofuels)
*Dennis Keeney, PhD, MS (Founding Director, Aldo Leopold Center, distinguished soil scientist, and CLF Visiting Scholar)

Precautionary Principle
n 
Rio Declaration on Environment and Development, 1992
- 
n 
Principle 15: “In order to protect the environment, the
precautionary approach shall be widely applied by States
according to their capabilities”
Wingspread conference, 1998
-  “When an activity raises threats of harm to human health or the
environment, precautionary measures should be taken even if
some cause-and-effect relationships are not fully established
scientifically.”
- 
“In this context the proponent of an activity, rather than the
public, should bear the burden of proof.”

Feeding a Growing World Population in a Livable Future
n 
Small holder farming and economically viable agricultural
economies
- 
500 million smallholder farms worldwide support 2 billion
people
- 
GDP growth originating in agriculture is at least twice as
effective in reducing poverty as GDP growth originating outside
agriculture
- 
- 
- 
Based on agroecology with a diversity of crops and livestock
“Sustainable intensification”—higher yields with fewer resources
Reinvestment by governments, NGOs, private sector
 
- 
Technology should be free, based on best-practices and
science

Feeding a Growing World Population in a Livable Future
n 
Improvements in infrastructure: roads to access markets, storage
and refrigeration, surplus
n 
Global shift in dietary consumption patterns
- 
- 
Decreased meat (grain) consumption in high-income countries
Greater access to sustainably produced iron- and protein-rich
animal food sources in the least developed countries

Resilience, a New Word for “Sustainability?”
1.  The power or ability to return to the original form, position, etc.,
after being bent, compressed, or stretched; elasticity
2.  Ability to recover readily from illness, depression, adversity, or the
like; buoyancy

and man is one great subject”
