Cow products are the worst!
Nearly 87% of our agricultural land(50% for cows alone!) is engaged in
animal production for food

U.S. Crop % that goes to feed
cows 80 - 90% of our
soybeans, oats,
wheat and corn
What! You have a problem with
that?

Cow efficiency
It takes 16 lbs of wheat to make 1 lb of
cow
5000 gallons of water per lb of cow (A lb of soybeans only takes about 260
gallons of water)

A typical North American Diet requires twiceas much water to produce as less meat-
intensive diets common in Asia and Europe.
Eating lower on food chain : same water
could feed double the people
Making animal products use ½ the water in
US
1 dairy cow drinks about 29 gallons of water a day, and needs 40 additional gallons for
sanitation, producing only 8 gallons of milk
Got Water?

Pollution (Deep Doo-Doo!)
EPA : agricultural runoff = primary pollution source for 60% of U.S. polluted rivers and streams
Animal ag. = 130 times more than human waste and
equivalent to 5 tons per person.
AND ITS NOT TREATED BY A SEWAGE TREATMENT
PLANT!
The manure from a 200-head dairy operation produces
as much nitrogen as sewage from a town of 10,000
people!
One dairy cow produces 120 lbs of waste a day, 12times as much as a person
This is a total of 22 tons per cow per year .

Got Trees?
Eating a plant based
diet personally saves
an acre of treesannually
260 million acres of
U.S. forests have
been cleared for livestock production.

Our foreign suppliers
Throughout Central and South America,grazing and feed grain production are the
leading economic forces behind rainforest
destruction.
Every quarter lb hamburger costs Mother Nature 55 square feet of forest land!
U.S. is the world¶s top beef importer .
A fast food restaurant can claim to buy
from a U.S. supplier but suppliers are not
required to declare the nation
of origin of their products.

Got Petroleum?
Americans consume nearly as much fossil
fuels at the supermarket as at the gas pump.
The typical American burns about 530
gallons of gas each year driving.
Eating a meat based diet gobbles up an
additional 400 gallons of oil.

One acre of corn requires 140 gallons
of oil to produce.
Eating corn directly maximizes theenergy investment.
If the corn goes to livestock, only
about a fifth of the protein is returned
as food, four-fifths is lost

Additional tidbits
One quarter of all antibiotics produced areused in the U.S. for food animals
Foreign originated veggies may have beensprayed with DDT
L. A. water is full of DDT, washed off fromforeign fruits and veggies!
DDT is stored in fat ± linked to breastcancer (90% breast cancer patients haveDDT in their systems)
