Can We Continue to Feed the World?
|
Issues and Background
Our current global population, currently about 6 billion people,
is expected to increase by more than one quarter over the next two decades.
We must find ways to increase food production to sustain growing populations
in developing countries. But this challenge must be accomplished without
major increases in the amount of new land under cultivation, which would
further threaten forests and biodiversity, and without resorting to unsustainable
farming practices.
~ Ian Johnson
One of the most sacred illusions of America is that its agriculture
is above all reproach. Not only is the United States the “breadbasket
of the world”, but the developing world is somehow incapable of
emulating America’s productive farming methods. There is one thing
Americans are sure about, without their food and generosity, much of the
rest of the world would starve.
~from Unequal Trades in Agriculture
Many people see the consumption of meat as a symbol of affluence; the
more meat we eat, the better off we are. Others would advocate that we
stop eating meat altogether. Those that suggest we stop eating meat generally
do so for one of two reasons. Many believe it is morally wrong to eat
meat, citing that animals have rights just like the rest of us, while
others maintain that it is more environmentally friendly to not eat meat.
Not eating meat could extend the world’s food supply.
If we look at data from the Food and Agriculture Organization of the
United Nations we find that as of 1998 on average every man, woman and
child on the earth eats 37.7 kg of meat per year, which includes beef,
pork, poultry and other meats. So we ask the question, is 37.7 kg per
person per year a large amount of meat and could we feed more people if
we didn’t eat it? Without any point of reference it’s difficult
to answer this question. So, let’s for a minute assume that the
37.7 kg is all beef, which is about 83 lb per year or about 0.23 lb per
day; roughly a quarter-pound hamburger per day. There is however, great
disparity in the amount of meat consumed around the globe. For example,
meat consumption in Bangladesh is about 1/11 of the world average, while
that in the U.S. is approximately 3 times the world average.
Raising livestock for human consumption requires enormous amounts of
grain. For the last forty years approximately 37% of the world’s
annual grain harvest has been fed to livestock. However, in the United
States the percentage of grain (excluding exports) fed to livestock is
closer to 90%. The same is true for other affluent developed countries.
David Pimentel in his book Food, Energy and Society (University Press
of Colorado, 1996) suggests that rather than feed grain to livestock,
we should let the livestock eat grass and divert the grain to human consumption.
He estimates that for every 130 million tons of diverted grain we could
feed an additional 400 million people. In other words, we could feed an
additional 2 billion people worldwide if grain fed to livestock was diverted
to human consumption.
As economies expand, citizens have higher expectations for themselves,
their families and their governments. They also have more money to spend
and as a result expect to be able to consume more meat and meat products.
The Chinese government would like to double the per capita consumption
of eggs by the Chinese people from 100 to 200. In order to meet this new
demand, China would have to have approximately one egg-laying chicken
per person or about 1.5 billion chickens. As a result, China’s demand
for grain to feed those chickens will eventually outstrip the world’s
total supply of grain.
This entire analysis though, ignores the fact that raising livestock,
whether grass-fed or grain-fed, creates huge environmental problems. In
the state of Oregon, 25,000 dairy cattle produce 300,000 gallons of waste
every day! Many of the area’s oyster growers blame contamination
from the manure for closing shellfish harvesting for 50 to 90 days a year,
thus directly affecting their livelihood. During a storm in the summer
of 1995, 25 million gallons of concentrated swine manure and urine contaminated
the New River in North Carolina as well as the New River Estuary. Increased
oxygen demand and enormous blooms of algae thrived for three months after
the discharge killing thousands of fish along the river and some 10,000
Atlantic menhaden at the site of a Pfiesteria outbreak.
Undoubtedly, the farmers of the world, including large corporate farming
empires, need to strike a balance between feeding the masses and destroying
the land on which their business depends. Let’s hope it isn’t
too late.
Primary Resources and Data
Food and Agriculture Organization of the United Nations (FAO)
http://www.fao.org
A very informative site with a large amount of data available in searchable
databases, though the databases could be a little more user-friendly.
United States Department of Agriculture
http://www.usda.gov
When President Abraham Lincoln founded the Department of Agriculture in
1862, I’m sure he never envisioned his “people’s Department”
as reaching the people quite so easily as through the Department’s
website. Lot’s of information here, including sections on food safety
and the new 2002 Farm Security and Rural Investment Act (i.e. the Farm
Act).
EarthTrends at the World Resources Institute
http://earthtrends.wri.org/
This is an excellent site with more information in searchable databases
than you could ever imagine needing. For environmental data this is usually
the first place I look.
Unequal Trades in Agriculture
http://www.ied.info/books/ed/agricultural.html
This is a chapter from the book “Economic Democracy: The Political
Struggle of the Twenty-first Century” by J.W. Smith found at the
site of the Institute for Economic Democracy. The article does a good
job of making the case against U.S. agricultural products.
Different Perspectives in the Debate
Ecological and Economic Consequences of Meat Consumption
http://www.vegetarismus.ch/info/eoeko.htm
This is a well-written article on the consequences of eating meat. The
author outlines several problem areas, including the destruction of forests
by manure, the destruction of water and the over-acidification of the
soil.
Humanity’s Evolutionary Diet and Ape Diets
http://www.beyondveg.com/nicholson-w/hb/hb-interview1b.shtml
This article tries to dispel the vegetarian point of view that humans
were not designed to meat eaters. The article is a transcript of an interview
with Ward Nicholson the founder of the Natural Hygiene movement. Interesting
reading.
Organic Farming Will Feed the World
http://www.psrast.org/orgfarmmonbiot.htm
The author describes how organic farming is more productive than high-tech
agriculture, but loses points from me for sounding a bit too conspiratorial.
U.S. Food and Agriculture Policy: A Failed Concept or a Conspiracy?
http://www.farmersoption.com/
Leonard Schnell is a retired farmer and in this article gives his take
on the U.S. farm industry and the steps necessary to fix it. Addressing
the many farm recessions that family farmers have had to face, he says,
“Like a hot wind in summer, it brings with it a new plague, a pestilence
of plenty, that threatens the independent status of the farming industry.”
An interesting perspective.
Disturbing Facts On Factory Farming & Food Safety
http://OrganicConsumers.org/Toxic/factoryfarm.cfm
This is essentially a laundry list of facts about the relationship between
factory farming and antibiotics, water pollution, animal welfare, economics,
public health and sustainability. All of the facts listed have source
citations where more information can be found.
Animal Farming and the Environment
http://www.ivu.org/oxveg/Talks/animalfarmenv.html
Found on the Oxford Vegetarians Website, this article gives more facts
and figures about the environmental damage caused by animal farming. The
article also offers some solutions to the problems.
Potential Impacts of Climate Change on Agriculture and Food Supply
http://www.gcrio.org/CONSEQUENCES/summer95/agriculture.html
In this article from the online journal, CONSEQUENCES, the authors, rather
than report on how farming affects the environment, describe the effect
of the environment on farming. The article paints a rather interesting
scenario.
Food and the Environment
http://www.ucsusa.org/food_and_environment/index.cfm
In several articles, the Union of Concerned Scientists takes a look at
large-scale industrial agriculture, genetic modification of food, organic
farming and sustainable agriculture. This is an excellent site and as
usual the UCS does a great job of giving us a clear picture of what’s
going on.
Organic Farming: Facing Choices at the Crossroads
http://www.pmac.net/xroad.htm
In this article, Dr. Charles Benbrook of the University of Guelph gives
an excellent treatise on organic farming.
