Recent blog posts on the SOYMB blog have not been an attempt to
promote the eradication of meat from the personal diet, but to present an
argument for the preservation of the environment, which includes a decrease in
current levels of consumption, as well a change in farming practices, that we feel will be an inevitable in a rational
socialist society.
Most people are not aware that beef production is directly
responsible for producing vast levels of greenhouse gases and expanding
deforestation, especially in the Amazon forest region. In fact, in the past 25
years forests with an area the size of India have been cleared in Central and
South America. Although demand for beef has stagnated in the U.S. and certain
Latin American countries, worldwide consumption continues to expand, and
producers in the Western hemisphere are eager to supply. In fact, the Food and
Agriculture Organization (FAO) predicts that beef production and consumption
will double by 2050, a situation that can ultimately be costly to the
environment. According to the Worldwatch Institute, “Over the last 30 years,
the number of farm animals – and that includes both four-footed livestock like
cattle and pigs and goats and sheep, as well as poultry – has increased about
23 percent since 1980.”
There are two predominant techniques employed to raise cows.
One method, called grazing, allows cattle to wander throughout enclosed
grasslands. Grazing is considered more humane; cows are free to roam the land
before heading to the slaughterhouse. Grazing methods imply that cows eat
mostly grass and are not given antibiotics, hormones, or supplements. Of
course, there are variations to these methods, such as feeding cows with grains
and vitamins during the final stages of their lives to accelerate growth.
Raising livestock naturally is an extremely slow process and utilizes large
amounts of water and land in order to achieve an optimal beef weight. It takes
much longer to raise a cow naturally, and consequently more resources are used
for its growth. In the past 40 years, vast areas of forests have been destroyed
to give way to agriculture and cattle ranching. In addition, cows produce large
amounts of natural waste that contains methane, a greenhouse gas that is
harmful to the environment. Methane accounts to 18 percent of all greenhouse
gases, and livestock waste is three times more potent than human waste. At
least through grazing, cows sequester carbon emissions on the pasture and this
results in better air and water quality than feedlots.
Grazing requires vast tracts of land that are utilized
solely for the cows’ livelihood, but yield little production as they take years
to mature. As a result, farmers are encouraged to use the land to plant corn or
soy, products that have a higher demand. Instead of grazing, they turn to
feedlots, which confine the cows in concentrated animal feeding operations
(CAFOs), the second technique. Cows in feedlots are fed on a corn and soy diet,
amongst other grains, even though these are not part of a natural diet for
cattle. In many feedlots, cows are administered hormones and antibiotics to
speed growth. The total lifespan of the cow is shorter, which means less use of
water, food, and land. However, cows produce methane and large concentrations
of these gases harm the environment. In addition, a shorter lifespan means more
beef is produced, since this allows more cows to move through the feedlots.
Studies show that red meat is linked to heart disease and
cancer. In a study, heavy consumers of red meat were associated with low
physical activity, smoking, and higher body mass. Corn is not the natural food
of cows, and therefore grain-fed beef contains about 22-39 percent more
cholesterol. Grass-fed beef is healthier because it has higher levels of
linoleic acid and omega-3. There is no perfect way to raise cattle, but given
the choice, grass-fed is healthier and friendlier to the environment.
Changing farming practices can increase the fertility of the
land and reduce gas emissions. One example is Estancia Grass-fed Beef that
works with the traditional Argentine model of cattle grazing. It involves a
rotating system of 5-7 years of cattle ranching followed by 1-2 year crop
cycle. Their model maintains the fertility of the soil and avoids monoculture,
a dangerous method that deprives the soil of its nutrients.
