Sustainable livestock production is an alternative to
standard production methods which provides a reasonable rate
of return to the farmer while taking into account the
impacts that livestock operations have on local communities
and the environment. To be sustainable, an intensive
livestock operation must consider the availability of
resources (feed, land, water), the ability of the
environment to safely absorb wastes, human and animal health
concerns, and the direct effect that the operation will have
on the local community. In its current form, the CAFO industry is not
sustainable. Here are some reasons why: Overstocking and environmental contamination: In
the days of small "Mom and Pop" farms, it was natural to let
animals dispose of their waste on farm land as a way to
supply cheap fertilizer to the soil. Now, however, the
higher concentration of animals in CAFOs means waste
(especially nitrogen and phosphorus) is generated and cycled
in excess through the air, water, and land, overburdening
the ecosystem's capacity to utilize it. For example, the
amount of land needed to efficiently distribute the manure
generated in a typical intensive cattle feedlot is 1000
times larger than the feedlot itself.1 Most CAFOs do not
have this much land available for manure application, so the
excess may be over-applied to a smaller area. To make
matters worse, there are few national and state regulations
that set specific requirements for applying manure on land.2
Texas regulations state that land application of wastewater
from lagoons "shall not exceed the nutrient uptake of the
crop coverage," however this amount is calculated on a
case-by-case basis.3 And waste application may still exceed
crop requirements if a CAFO submits a "Nutrient Utilization
Plan" which justifies its waste management practices.4 Human health impacts: Industries that pose significant
threats to human health are not sustainable. The health
impacts of CAFOs can be seen at many levels. Dust and odors
contribute to respiratory problems in workers and nearby
residents. Contamination from runoff or lagoon leakage
degrades water resources and can contribute to illness by
exposing people to wastes and pathogens in their drinking
water. Finally, the misuse of antibiotics in animal
production systems results in the development of
antibiotic-resistant pathogens which may be passed through
the food chain to humans. Negative impact on local communities: CAFOs that
contaminate air and water resources have a direct impact on
the health and well-being of nearby communities. At the same
time, odors from CAFOs can drive down property values5 and
force some long-time residents to leave, as noted in this
report. And the evidence is unclear whether CAFOs really do
enhance the local economy. Larger, more mechanized farms may
actually worsen community conditions because they may hire
migratory agricultural workers for low wages6 (and with no
promise of adequate housing), purchase feed and supplies
outside of the local area (thereby draining economic
resources away from the community), and eventually drive out
family farms that can no longer compete.7 What could be expected from a sustainable livestock
production system? It can be envisioned as an integrated and
holistic approach: human labor and resources are substituted
for capital and commercial inputs; externalities such as
pollution 'costs' are considered and weighed against the
economic benefits (i.e. profit) of the facility; stocking
densities do not compromise animal health and well-being;
waste production does not exceed the nutrient-absorbing
capacity of the surrounding land or jeopardize water
quality; forage crops are grown on-site or nearby to promote
self-sufficiency and less reliance on outside feed
shipments; and rural communities are strengthened and
empowered. Given the commitment and the will, livestock
producers have the resources and knowledge to begin this
transition to sustainability today. 1 Carpenter, Stephen, et al., "Nonpoint pollution of surface waters with phosphorus and nitrogen," Ecological Applications, Vol. 8, No. 3 (August 1998), p. 563. 2 Corpus Christi Caller Times, "Manure problem growing: Animal waste a health concern," April 26, 1998. 3 30 T.A.C. § 321.39(f)(19)(B). 4 30 T.A.C. § 321.39(f)(28)(G). 5 Palmquist, Raymond B., et al., "Hog operations, environmental effects, and residential property values," Land Economics, Vol. 73, No. 1 (February 1997), pp.114-124; Mubarak, Hamed, Thomas G.
