How Our Food
Choices Can Help Save the Environment
From a speech delivered to EarthSave Baltimore
by Professor Steve Boyan
The Union of Concerned Scientists
says that the two things that people can do which will most help
the environment are (1) to drive a fuel efficient automobile (that
means, not a SUV or a truck), along with a decision to live near
to where you work. That recommendation is indeed important.
Anything you can do either in what you drive or where you live is
important. The 2nd thing the Union of Concerned Scientists
proposed that people could do which also would have dramatically
good consequences for the environment: to not eat beef.
I'm going to go one step farther than UCS:
I suggest that you
refuse to eat any animal or animal product produced on a factory
farm. And I'm going to tell you why.
In 1990,
when I first read, that 10 people could be fed with the grain that
you would feed a cow that would be turned into food for one
person, I was impressed. But I was not moved. The reason was: if
10 people would be fed because I gave up meat, I'd give it up.
But, I thought, if I give up meat, it won't have that impact: it
probably won't have any impact on anything at all, except me.
I was wrong.
If I had known that for every pound of beef I did not eat, I would
save anywhere from 2500 to 5000 gallons of water - you heard it,
for every pound of beef, 2500 to 5000 gallons of water, I would
have been moved. It's a good idea to save water; we are depleting
our underground aquifers faster than we are replenishing them. The
largest one, the Ogallala, which covers a vast part of the country
from the mid-west to the mountain states, is being depleted by 13
trillion gallons a year. It is going to run out. Northwest Texas
is already dry. They can't get any water from their wells.
John Robbins points out that in the 1980's and 1990's,
to conserve water, most of us went to low flow showerheads. If we
take a daily 7 minute shower, he says, and we have a 2 gallon per
minute low flow showerhead, you use about 100 gallons of water per
week, or 5200 gallons of water per year. If you had used the old
fashioned 3 gallon per minute showerhead, I calculate you would
have used 7644 gallons of water per year. So by going low flow,
you saved almost 2500 gallons of water per year. Wonderful. But by
giving up one pound of beef that year, you'd save maybe double
that. By giving up one pound of beef, you'd save more water than
you would than by not showering at all for six months! And that's
just one of the environmental impacts you'd have.
The modern factory farming system
is a prolific consumer of fossil fuel and a prolific producer of
poisonous wastes. Up to 100,000 animals are herded together on
huge feedlots. These animals do not graze on grass, as picture
books tell us; they can't graze at all. They are crowded, filthy,
and stinking places with open sewers, unpaved roads, and choking
air. The animals would not survive at all but for the fact that
they are fed huge amounts of antibiotics.
It is now conceded
that the antibiotics fed to cattle are the main cause of
antibiotic resistance in people, as the bacteria constantly in
these environments evolve to survive them. The cattle are fed
prodigious quantities of corn. At a feedlot of a mere 37,000 cows,
25 tons of corn is dumped every hour. It takes 1.2 gallons of oil
to make the fertilizer used for each bushel of that corn. Before a
cow is slaughtered, she will eat 25 pounds of corn a day; by the
time she is slaughtered she will be over 1200 lbs. In her lifetime
she will have consumed 284 gallons of oil. Today's factory raised
cow is not a solar powered ruminant but another fossil fuel
machine.
And she will produce waste.
Livestock now produces 130 times the amount of waste that people
do. This waste is untreated and unsanitary. It bubbles with
chemicals and disease-bearing organisms. It overpowers nature's
ability to clean it up. It's poisoning rivers, killing fish, and
getting into human drinking water. 65% of California's population
is threatened by pollution in drinking water just from dairy cow
manure. It isn't just cows that produce this waste. Factory raised
hogs produce 4 times the waste in North Carolina as the 6.5
million people of that state do. Cases of pfiesteria have broken out in that state and even
here in Maryland - from water polluted from pig farms and chicken
farms. Even the oceans are polluted: 7000 sq. miles of the Gulf of
Mexico are a complete dead zone.
There are more environmental impacts.
Cattle don't spend their entire lives in feedlots. When they are
young, they graze. Where do they graze? Well, more than 2/3rds of
the land area of the mountain states are used for grazing. 70% of
the lands in western national forests are grazed; 90% of Bureau of
Land Management land is grazed. These are public lands, lands that
President Clinton didn't even try to save. These lands are
trampled by the cattle, compacting the soil. When it rains, the
land doesn't absorb the water. Instead, it runs off, taking away
topsoil, forming deep gullies, and damaging streambeds. Your tax
dollar subsidizes this activity. The government protects the
cattle by killing off any creature which might threaten the
livestock. They poison, trap, snare, den, shoot, or gun down the
wildlife. Denning, by the way, is the practice by federal agents
of pouring kerosene into the dens of animals and setting them on
fire, burning the young animals alive in their nests.
According to Robbins,
agents kill badgers, black bear, bobcats, coyotes, gray fox, red
fox, mountain lions, opossums, raccoons, skunks, beavers,
porcupines, prairie dogs, black birds, cattle egrets, and
starlings using these methods. These activities are on public
lands, which were created in large part to protect the
environment!
I'm not done yet.
We in the United States do not get all of our beef from the west.
We import more than 200 million pounds of beef from Central
America alone. Every second of every day, 1 football field of
tropical rainforest is destroyed in order to produce 257
hamburgers. A ¼ lb hamburger destroys 67 square feet of
rainforest. Every time you destroy rainforest land, you destroy
rich plant and animal life, varieties of life we don't even
understand, and forms of which may provide the medicines we need
to cure disease. Rainforests supply us with oxygen. They moderate
our climates. When rainforests are destroyed, it's only a matter
of time before the land becomes desert. They absorb some of the
carbon dioxide we are spewing into the atmosphere.
We humans have increased the amount of carbon dioxide
in the atmosphere by 25%, compared to any other period when humans
were on this planet. Most of that gain has taken place in the last
50 years. The Intergovernmental Panel on Climate Change,
consisting of some of the best scientists in the world, says
global warming is a fact. If uncontrolled, we will have ecosystem
collapses, crop failures, weather disasters, coastal flooding, the
spreading of previously controlled diseases, the death of coral
reefs, and new insect pests. Some of these things are starting to
happen already. Coral reefs are dying. Insect pests are spreading
out of their range and killing off new kinds of trees. Weather
patterns are changing. Some places have had extreme weather
events, with billions of dollars of losses. Some island people
have had to abandon their islands because rising seas have
salivated their underground aquifers.
Carbon dioxide is largely produced by the burning of fossil fuels,
especially coal, and especially our use of inefficient vehicles
for transportation. But not often mentioned is the fossil fuel
used to raise farm animals. As I said earlier, a factory cow is a
fossil fuel machine, not a solar powered ruminant whose wastes
fertilize the fields to produce more grass for the cow to eat.
When you eat beans, for example, you use 1/27th the amount of
fossil fuel to produce a calorie of energy as you do when you eat
beef. You get the same food energy producing only 4% of the carbon
dioxide that a person eating beef does.
There's another major environmental consequence
of our factory system of animal raising: that's the matter of
species extinctions. Now it is true that species die off all the
time. Normally, the earth has lost 10 to 25 species per year. But
in the billions of years of life on this earth, we have had 5
periods of major extinctions; the last one was 67 million years
ago, when, possibly because of a meteor colliding with the earth,
we lost the dinosaurs. But now there's a sixth extinction, and it
is not caused by a meteor, but by human beings.
And this is a big one;
we are losing several thousand species per year, and maybe tens of
thousands. We think of mammals that are endangered, and 25% of
mammalian species are endangered. But what's much more endangered,
or wiped out already, are the plants, including varieties of
plankton, fungi, bacteria, and insects, that are fundamental to
all so-called higher forms of life. All life will unravel if these
creatures are wiped out.
The driving force behind all these extinctions is the destruction
of wildlife habitat, especially the rainforests of the world. The
driving force behind the destruction of the rainforests is
livestock grazing. The leading cause of species in the United
States being threatened or eliminated is livestock grazing. A 1997
study of endangered species in the southwestern United States by
the Fish and Wildlife Service found that half the species studied
were threatened by cattle ranching.
You know, you and I cannot change all this.
We are not going to be able to get a bill through Congress
outlawing factory farming. Yet Earthsave as an organization believes we can still have a dramatic
effect: we believe that you can protect your health and protect
the environment one bite at a time. Let's review what I've said
here: by not eating beef - and other farm animals as well - you :
-
Save massive amounts of water - 3000 to 5000 gallons of water
for every pound of beef you avoid
-
Avoid polluting our streams and rivers better than any other
single recycling effort you do
-
Avoid the destruction of topsoil
-
Avoid the destruction of tropical forest: remember passing up ¼
lb of hamburger averts the destruction of 67 sq ft of rainforest
-
Avoid the production of carbon dioxide. Your average car
produces 3 kg/day of CO2. To clear rainforest to produce beef
for one hamburger produces 75 kilograms of CO2. Eating one lb of
hamburger does the same damage as driving your car for over 3
weeks.
-
Reduces the amount of methane gas produced. I imagine the next
bumper sticker: stop farts, don't eat beef.
-
Reduces the destruction of wildlife habitat
-
Help to save endangered species.
That's a pretty good day's work, for just what you don't put in
your mouth!
How does
eating meat harm our planet?
Eating meat leaves behind an environmental toll that generations
to come will be forced to pay.
Land: Of all agricultural land in the U.S., 87 percent is used to
raise animals for food—that’s 45 percent of the total land mass in
the U.S.
Water: More than half of all the water consumed in the U.S. for
all purposes is used to raise animals for food. It takes 2,500
gallons of water to produce a pound of meat but only 25 gallons to
produce a pound of wheat. A totally vegetarian diet requires 300
gallons of water per day, while a meat-eating diet requires more
than 4,000 gallons of water per day.
Pollution: Raising animals for food causes more water pollution in
the U.S. than any other industry because animals raised for food
produce 130 times the excrement of the entire human
population—87,000 pounds per second! Much of the waste from
factory farms and slaughterhouses flows into streams and rivers,
contaminating water sources.
Energy: Of all raw materials and fossil fuels used in the U.S.,
more than one-third is used to raise animals for food. Producing a
single hamburger patty takes enough fossil fuel to drive a small
car 20 miles and enough water for 17 showers.
Deforestation: Each vegetarian saves an acre of trees every year!
More than 260 million acres of U.S. forest have been cleared to
grow crops to feed animals raised for meat, and another acre of
trees disappears every eight seconds. The tropical rain forests
are also being destroyed to create grazing land for cattle.
Fifty-five square feet of rain forest may be razed to produce just
one quarter-pound burger.
Resources: In the U.S., animals raised for food are fed more than
80 percent of the corn we grow and more than 95 percent of the
oats. The world’s cattle alone consume a quantity of food equal to
the caloric needs of 8.7 billion people—more than the entire human
population on Earth. |
