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)
