Organic Agriculture
ORGANIC AGRICULTURE
The
impact of twentieth century agricultural changes is at least as profound as the
effects of such inventions as cars, television and computers.One hundred years ago, all of our food was
organically grown.That is, it was
grown without toxic pesticides and chemical fertilizers.Modern farm chemicals simply had not
been developed.
Many
more people lived close to the land on small, family-owned farms.The average life span was shorter than
it is today.However, that was
because many died in childhood.If
one lived to adulthood, the life span was about the same as today, without the
need for operations and modern drugs.Cancer and heart disease were minor problems - and people ate plenty of
red meat.
THE GREEN REVOLUTION
The
green revolution is the name given to the changes that revolutionized
agriculture in the twentieth century.Scientists discovered that fertilizing plants with super phosphate
fertilizers, sometimes called N-P-K fertilizers, stimulated plant growth and
increased crop yields.Hybrid
crops were also developed that enhanced crop yields.The combination increased food production per acre up to 10
times!
The
mineral content of the soil remained the same, however.So the mineral content of each plant
declined dramatically.The new
crops were also weaker and more vulnerable to pests and diseases.Scientists then developed modern
pesticides to kill the bugs.
Along
with high-yield crops and chemical sprays, mechanization was introduced to
agriculture.Because a large
acreage of one crop is easier for a machine to plant and harvest, monoculture
or one-crop farming became more common.This also made crops more vulnerable to pests, which increased the use
of the toxic sprays.With heavy
equipment, one farmer could cultivate thousands of acres.Many fewer people were needed on farms.The mechanized farms were more
efficient, so small farmers began to go out of business by the thousands and
the industry consolidated.
Thus
was born what is called agribusiness.These are large companies that own or control huge farms and expensive
equipment, produce the pesticides and fertilizers, and distribute food
worldwide.Combined with other
twentieth century inventions such as refrigeration and high-speed travel, the
Green Revolution radically changed food production and distribution.
A MIXED SUCCESS
The
Green Revolution succeeded in drastically increasing the amount of food
grown.American farms feed
millions more people around the world. Our government pays farmers millions
each year not to grow certain crops to keep the prices up. We also
have access to fresh pineapples from Hawaii or Malaysia, tomatoes from
Colombia, even rain forest herbs.Fresh food can be shipped virtually anywhere on earth in a few days.
The
Green Revolution also succeeded in increasing the efficiency of farming, if
that is measured in human labor required to grow food.It also succeeded in reducing human
drudgery - the hard, relentless manual labor required for non-mechanized
farming.
However,
not all changes have been positive.Modern agriculture requires huge investments in machinery, fuel,
chemical sprays and fertilizers.Other difficulties and costs to society may be far greater.
Chemical
Poisoning.The U.S.
Environmental Protection Agency considers pesticide poisoning the worst
environmental problem in the world.Pesticides have contaminated almost all water supplies in our nation,
decimated dozens of animal species, and polluted every aspect of our
environment.Most are cumulative
and carcinogenic.The American
Cancer Society estimates that 85% of cancers are environmentally caused.The cost of this epidemic is enormous.
Some
pesticides cause genetic damage similar to the effects of atomic fallout.This may contribute to a doubling of
the birth defect rate in America since 1950.Other pesticides mimic estrogen, which may contribute to
many cancers and other health problems.By killing soil microorganisms, herbicides and pesticides contribute to
massive soil erosion and loss of precious topsoil around the world, even
creating deserts in some areas.
Nutritional
Depletion.Few people
realize how devastating chemical agriculture has been to the nutrient content
of our food.The average
supermarket apple or tomato today bears little resemblance to one grown 100 years ago.This was the subject of a book written
in the 1980's called Food For Naught, The Decline in Nutrition
by Ross Hume Hall.
According
to the USDA, the calcium content of an apple has declined from 13.5 mg in 1914
to 7 mg in 1992.The iron content
has declined from 4.6 mg in 1914 to 0.18 mg in 1992.Some nutrition books written 50 or 60 years ago simply do
not apply to today's food.For
example, some people think they can live comfortably on the protein in pasta or
other wheat products because they read this in books.However, today's wheat has about half the protein content of
wheat grown just 80 years ago.The
use of pesticides and stimulant fertilizers has allowed poor-quality crops that
would otherwise have been destroyed by pests to make it to market.
Mass
production of chicken, beef, pork and other products often results in unhealthy
animals who receive over half the antibiotics used in America.Residues of these and other other drugs
used in food production find their way into our meat, eggs, and dairy products.
A
study published in the Journal of Applied Nutrition,
Vol. 45, #1, 1993, pp. 35-39 compared the nutrient content of supermarket food
versus organically grown food from food stores in the Chicago area.The organic produce averaged twice the
mineral content of the supermarket food!Fortunately, the organic food industry is growing rapidly, as the truth
about our nutritionally-depleted food becomes more widely known.
Health
Disasters and Starvation.Along with the green revolution has come "the diseases of
civilization".Authorities
are realizing that costly epidemics of heart disease, cancer, diabetes, AIDS,
mental illness and even violence are related to the nutritional content of the
food, and toxic substances in the food, water and air.
Social
Displacement. Factory
farming forced millions of people off their land and into the cities seeking
work.Life on the farm was not
easy, but living on the land provided a source of security, and a far healthier
environment than many city environments.Many people today cannot even afford the food that is grown on what was
their land.Living on the land has
been replaced by ghetto tenements in many nations including America.
TWO TRENDS
On one hand, the green revolution continues in full
swing, with ever newer technologies to produce more and cheaper food.Genetically engineered foods and food
irradiation are two of the newer technologies.New drugs are developed to handle the new plant, animal and
human diseases that result from consuming the chemically-grown foods..
The
other trend is the growth of organic, sustainable, or ecological agriculture,
the environmental movement, the locally grown movement, land trusts, and seed
banking.
GENETICALLY ENGINEERED (GE) FOODS
Genetic
engineering involves adding, deleting or changing specific genes in a plant to
produce certain qualities in the plant.Genetic modification is not new.Crops have always been crossbred to produce tastier, hardier, more
nutritious varieties of food.Indeed, our present foods were bred from wild plants by generations of
farmers who carefully picked the best of their crop to produce the next year's
crop.
The
new genetic methods are more specific, work much faster, and for the first time
companies are patenting their new varieties to give them control over who grows
the crops.
As
with any new technology, there are potential problems with GE.For example, some G-E plants make their
own toxic pesticides.In a recent
incident, Bt corn, bred to produce a pesticide to kill corn borers, also killed
monarch butterflies that ate the pollen.It won't kill humans outright, but what are the health effects?Thirty percent of the corn grown in
America in 1999 was genetically engineered Bt corn.
Roundup
Ready soybeans are bred to withstand more of the pesticide called Roundup.This means more pesticide can be
sprayed.This is excellent for the
pesticide producer.However, what
does the pesticide do to our bodies, water supplies, wildlife, and soil
microorganisms?
Another
controversial area of GE is called "terminator genes".These are genes that are added to the
plant so that it will not reproduce.This way, the farmer must buy new patented seeds from the company each
year, instead of saving seeds for next year,a common practice especially in poorer nations.In summary, there are potential
benefits of GE, such as improved drought-resistance or nutrition of crops.In practice, however, the focus of GE
is often on greater production and continued dependence on chemical methods of
agriculture.
Most
European nations, where more small farms remain, prohibit the importation of GE
foods or seeds.There is less concern
in America, although recently two large natural food retailers decided to stop
selling GE foods.Americans tend
to embrace new technology more readily, and in America chemical companies have
more influence. There is a campaign to insist on labeling of genetically
engineered foods.This is the only
way people will have a choice regarding what they are eating.
FOOD IRRADIATION
As
food is grown and shipped globally, avoiding spoilage is of great
importance.Food grown with
pesticides and chemical fertilizers often does not keep as well as the older,
hardier varieties.This has
spawned interest in newer methods of food preservation.Irradiation of plant and animal
products kills bacteria that can cause spoilage.
Problems
with food irradiation are the danger of damaging sensitive components of the
food, harm to workers, and disposing of spent radioactive material.Ionizing radiation is very harmful to
living matter.Also, food that
spoils easily is often of lesser quality.Preserving it with irradiation to make it edible does not make it
healthful to eat.The nutritional
and vitality of the food take a back seat to the desires of the processors to
avoid spoilage.
Irradiated
food in America is supposed to be labeled, although processed food often
contains irradiated ingredients that are not labeled.Labeling of GE foods and irradiated food is a critical issue
so that people have a choice.
ORGANIC AGRICULTURE
The
organic, sustainable and biodynamic agriculture movements in America and around
the world are the fastest growing area of agriculture.A recent study revealed one can grow
equal amounts of food without toxic pesticides and herbicides.One can raise animals without massive
use of antibiotics, female hormones and other drugs used on farm animals and
farm fish.
The
organic methods build up the soil, produce hardier crops that resist pests,
preserve the environment, and provide more nutritious food.The food may not look different, but it
has a longer shelf life and is nutritionally superior, as revealed in several
studies.
Offshoots
of the organic movement that are still in their infancy include the use of
organic cotton and hemp clothing.Half of all the pesticides are applied to cotton.Hemp requires no pesticides as it is a
hardier crop.It was a major crop
in America until it was banned in 1937. Hemp is an excellent source of fiber
for clothing, alcohol for fuel, and protein and oils for nutrition and
industrial applications.Hemp is
not the same variety as marijuana, and was not banned in America because of
drug abuse.It was banned because
it competed with the nylon industry for clothing manufacture.It also competed with oil for fuel, and
with the timber industry for paper-making.Hemp is grown commercially almost everywhere except the
United States.
LAND TRUSTS
Land
trusts are agreements made by individual land owners to prevent future
development on their land.The
trusts contain strict covenants for the land use, to prevent its use for
parking lots and shopping centers, for example. Buyers or renters of the land
must agree to abide by the contract.Though still a small movement, land trusts now exist in every part of
America.They are helping to save
farmland, wildlife habitats and old-growth forests from destruction.
SEED BANKS
As
new hybrid plants are used more widely, some of the older seed varieties are in
danger of being lost.Several
groups have taken on the task of saving and banking precious seeds. They could
be useful or even life-saving if weather changes or new crop diseases destroy
the hybrid or GE plants.Also, the
genetic material in the older seeds may be needed at some time to enhance our
crops.For research and for
disaster preparedness, the movement to save traditional seed varieties is an
important trend.
LOCALLY GROWN
More
small farmers are finding a niche catering to the needs of the local
community.Farmer's markets and
local buying clubs helps address the problem of the loss of the family farm.Communities are reaping the benefits of
supporting local farmers by getting fresher and often better quality
produce.Often the local farmers
grow food organically, helping preserve the land, the wildlife and the local
environment.The locally grown
movement also fosters a greater sense of community, and contributes to local
self-sufficiency and sovereignty.
We
are not going to go back to farming as it was done a century ago.However, it is possible to use modern
technology wisely to produce pure, nutritionally superior food without damaging
the environment.This is the
challenge for agriculture in the 21st century.
