Overview
• According to the UN Food & Agriculture Organiza8on, current global meat consump8on is at approximately 280 million tons per year1; this figure is expected to double by 2050 when the world’s popula8on is expected to reach 9.8 billion.2
• In this part of the presenta8on, we will focus our discussion on the industrialized produc8on and consump8on of beef in North America, and its subsequent environmental effects through the con8nued prolifera8on of concentrated animal feeding opera8ons, or factory farms.
• According to the US Department of Agriculture, in 2009, approximately 56.1 million metric tons of beef were consumed globally, with the largest consumers of beef in the world being the United States, followed by the European Union, Brazil and China.3
• However, in per capita terms4, -‐ Argen:na is the largest consumer of beef at ~65.6 kgs of beef per
person per year -‐ United States is 3rd at ~40.7 kgs of beef per person per year -‐ Canada is 6th at ~31.7 kgs of beef per person per year -‐ Mexico is 8th at ~24.1 kgs of beef per person per year.
• Since the 1950’s, this increase in meat consump8on globally has been encouraged by the prolifera8on of concentrated animal feeding opera:ons, or factory farms, with some 80 percent of growth in the livestock sector coming from mass industrial produc8on systems that consume vast amounts of feed and energy.5
Industrialized Beef Produc:on in North America
• These factory farms are large, high-‐density facili8es where hundreds to thousands of caale are confined in small spaces and fed mainly on a diet of grains. These grains range from cereal grains like corn, barley and wheat, to legume, hays (clover, soybeans, alfalfa) and grass hays (coastal Bermuda, fescue and blue grass); 6 all with the purpose of reducing costs for the producers through the achievement of economies of scale.
• Since caale in these factory farms are oden confined in very 8ght spaces, drugs, which include an8bio8cs, are oden mixed in with the caale supply feed and water, to promote growth and to keep the caale from geeng sick.

Factory Farms & CaKle Feed
• The con8nued use, or misuse of an8bio8cs such as Cephalosporins as growth promoters, not only in caale farms but in poultry and pork farms as well, has led to a drama8c increase in the resistance of an8bio8cs among people in North America, Europe and Asia.7 These an8bio8cs are important to us because they have the ability to knock out a wide range of hard-‐to-‐treat human ailments such as urinary tract infec8on and pneumonia. If we are growing increasingly resistant to an8bio8c drug treatment because of the food we eat, this poses a huge public health risk for us all. 8

• In the beginning of the 20th century, most animals were pasture-‐raised on family farms. However, by 2003, 82 percent of the caKle in the United States alone were produced by just four industrial producers.9 Some of the main underlying factors behind this transi8on from small family farms to large agribusiness producers, include the development of nitrogen fer8lizers as well as the availability of cheap corn made plen8ful by government subsidies that guaranteed a set price for corn.10
• At a 8me when land for grazing and feed crop produc8on occupies roughly 30 percent of the land surface of the planet, the con8nued prolifera8on of these concentrated animal feeding opera8ons will ul8mately lead to direct compe88on for already scarce land, water and other natural resources, not to men8on the nega8ve environmental consequences arising, from loss of biodiversity and deforesta8on, to the acidifica8on of terrestrial ecosystems and emissions of greenhouse gases.11
Environmental Consequences of Industrialized Beef Produc:on
Deforesta:on and Biodiversity Loss • As previously men8oned, land used in
agricultural produc:on occupies approximately 30 percent of the planet’s land surface. As meat demand increases worldwide, including the demand for beef, even more forests will be cleared for addi8onal livestock ac8vity and crop produc8on. As a serious consequence, na8ve species are being pushed out of their habitat and biodiversity is being lost.12

Deple:on of Water Resources • Aside from deforesta8on and loss of biodiversity, there is also the
serious issue of water deple8on as a result of con8nued industrialized beef produc8on. Approximately 2,500 gallons of water are required to produce a pound of beef, compared to 22 gallons to produce a pound of tomatoes.13 This figure takes into account the amount of water needed to harvest the grain to be fed to the caale, the water the caale need to drink, as well as the water required at slaughter.
Major Contributor to Greenhouse Gas Emissions • According to a report published by the UN FAO in 2006, livestock
produc8on causes 18 percent of all global manmade greenhouse gas emissions, which is more than all transporta8on services combined.14 This figure takes into account the fossil fuels required in feed produc8on; carbon dioxide emissions from forests cut down for addi8onal livestock ac8vity and crop produc8on; carbon dioxide emissions from the transporta8on of animal products; and nitrous oxide and methane emissions from caale belching and manure.
Air and Water Pollu:on • Livestock raised in factory farms, including caale, produce an enormous
amount of manure most of which is stored in large manure holding lagoons. The runoff of this waste into surface and groundwater has contaminated drinking water in many areas across North America; some manure lagoons have also given way, sending millions of gallons of raw waste into streams and estuaries.15 The runoff of manure, which contains nitrogen and phosphorus, eventually reaches larger water bodies where they can cause eutrophica:on, the prolifera:on and ensuing death of algae robbing the the water of oxygen, crea8ng dead zones where no living creatures can survive.16

Are there sustainable alterna:ves?
• Given all of the nega8ve environmental consequences surrounding concentrated animal feeding opera8ons, do sustainable alterna8ves exists?
• The answer is yes, sustainable alterna8ves to the industrialized produc8on system of beef do exist, such as smart pasture opera8ons (SPOs) producing pasture-‐raised beef.17
• In fact, the demand for pasture-‐raised beef is growing in the US, as is the demand for pasture-‐raised milk and cheese products.18

• Smart pasture opera8ons take advantage of low-‐cost grass grown on carefully managed pastures, requiring less maintenance, energy, pes8cides, and water than industrial beef produc8on. The smaller amount of manure produced also fer8lizes the land, avoiding water and air pollu8on. Grass-‐fed caale are also healthier and more gene8cally diverse, helping to prevent the spread of disease. In addi8on, grass-‐fed beef is healthier to eat; grass-‐fed beef and dairy products have less total fat and higher levels of good omega-‐3 faay acids compared to those from animals fed a grain diet.19
• And finally, on an individual consumer level, one way that we can reduce the environmental impact of the industrial produc8on of livestock, is to simply reduce our meat consump8on, as recommended by Dr. Rajendra Pachauri, chair of the UN Intergovernmental Panel on Climate Change.20 In addi8on, according to researchers at the University of Chicago, if Americans were to reduce their meat consump8on by just 20 percent, it would be as if everyone switched from a standard sedan to an ultra-‐efficient hybrid vehicle.21
