Hidden Costs of Industrial Agriculture
http://www.ucsusa.org/food_and_agriculture/science_and_impacts/impacts_industrial_agriculture/costs-and-benefits-of.html
Union of Concerned Scientists

Much of the agriculture practiced in the United States today is
industrial-style agriculture. That is, farms are often very large, highly
specialized, and run like factories with large inputs of fossil fuels,
pesticides and other chemicals, and synthetic fertilizers derived from oil.
This industrial agriculture is sometimes considered a great success. But is
it? It has had large, complex effects on our environment, our economy, and
our urban and rural social fabric. A new awareness of the costs is beginning
to suggest that the benefits are not as great as they formerly appeared.

Many of the costs of industrial agriculture have been hidden and ignored in
short-term calculations of profit and productivity, as practices have been
developed with a narrow focus on increased production. The research
establishment that underpins modern industrial agriculture has until recently
paid little heed to the unintended and long-term consequences of these
systems.

Damage to Natural Systems

Approaches to producing food must be measured partly by their impact on the
natural ("life support") systems that we depend on. The currently dominant
system of industrial agriculture – which voters and taxpayers have
unknowingly promoted and subsidized through ill-considered government food
and farm policy choices – impacts the environment in many ways. It uses huge
amounts of water, energy, and chemicals, often with little regard to
long-term adverse effects. But the environmental costs of agriculture are
mounting. Irrigation systems are pumping water from reservoirs faster than
they are being recharged. Toxic herbicides and insecticides are accumulating
in ground and surface waters. Chemical fertilizers are running off the fields
into water systems where they generate damaging blooms of oxygen-depleting
microorganisms that disrupt ecosystems and kill fish. Unmanageable and
polluting mountains of waste and noxious odor are the hallmarks of
industrial-style CAFOs (confined animal feeding operations) for poultry and
livestock.

Many of the negative effects of industrial agriculture extend far from fields
and farms. Nitrogen compounds from Midwestern farms, for example, travel down
the Mississippi to degrade coastal fisheries and create a large "dead zone"
in the Gulf of Mexico where aquatic life cannot survive. But other adverse
effects are showing up within agricultural production systems themselves --
for example, overuse of herbicides and insecticides has led to rapidly
developing resistance among pests that is rendering these chemicals
increasingly ineffective.

Economic Costs

Estimating the economic costs of industrial agriculture is an immense and
difficult task. A full accounting would weigh the benefits of the somewhat
lower prices consumers pay for food and the profits of agri-business giants,
including fertilizer and pesticide manufacturers, against the health and
societal costs of environmental pollution and degradation, for instance.

Such costs are difficult to assess for a number of reasons. One difficulty is
our partial understanding of potential harms. A good example is the potential
for endocrine disruption that many pesticides appear to have. Endocrine
disrupters are molecules that appear able to mimic the actions of human and
animal hormones and disturb important hormone-dependent activities like
reproduction. More research is needed to determine the extent of the health
and environmental damage done by such compounds and the relative contribution
of agriculture and other sectors and activities. And in some instances, such
as water pollution and global warming, agriculture is only one of several
important contributors.

Among the many environmental costs that need to be considered in a full cost
accounting of industrial agriculture are

* the damage to fisheries from oxygen-depleting microorganisms fed by
fertilizer runoff
* the cleanup of surface and groundwater polluted with CAFO waste
* the increased health risks borne by agricultural workers, farmers, and
rural communities exposed to pesticides and antibiotic resistant bacteria

In addition, there are enormous indirect costs implicit in the high energy
requirements of industrial agriculture. This form of agriculture uses fossil
fuels at many points: to run huge combines and harvesters, to produce and
transport pesticides and fertilizers, and to refrigerate and transport
perishable produce cross country and around the world. The use of fossil
fuels contributes to ozone pollution and global warming, which could exact a
high price on agriculture and the rest of society through increased violent
weather events, droughts and floods, and rising oceans.

The full costs of industrial agriculture—including the hidden costs of CAFOs
revealed by UCS in the recent report CAFOs Uncovered—call into question the
efficiency of this approach to food production.

Agriculture at a Crossroads

It is time to transform agriculture into a sustainable enterprise, one based
on systems that can be employed for centuries -- not decades -- without
undermining the resources on which agricultural productivity depends. The
question is how to do it. The choices are to stick with the current system
and adjust around the edges or to fundamentally rethink it. UCS is aiming for
the transformation of U.S. agriculture to a system that is both productive
and practical over the long-term. Apparent advantages of the current,
industrial approach – from high yields per acre, to chemical industry
profits, to profitable CAFOs (confined animal feeding operations), to foreign
sales by corporate giants like Sara Lee, ConAgra, and Cargill – look very
different when considered in the light of the health and other problems the
approach creates, as well as the many ways in which consumers actually
subsidize the destructive system with their tax dollars.
