ObjectivesLearners will be able to understand the positive and negative environmental
and economic effects of agriculture on United States water sources.
Learners will be able to distinguish between the difference between animal
vs plant agriculture impacts on water.
Learners will be able to understand how American culture influences water
diversion and use for plant and animal agriculture.

through man made systems to supply water requirements not satisfied by
rainfall.

WATER CONSUMPTIONHalf of all the water used in the United States goes to raising animals for
food
1,800 gallons of water to produce 1 lb of beef
25 gallons of water to produce 1 lb of wheat
Daily water consumption:
Meat eater- 4,000 gallons
Lacto-ovo vegetarian- 1,200 gallons
Vegetarian- 300 gallons

WHY SO MUCH WATER?1. Feed Conversion Ratios (CFR)
Animal’s efficiency to turn its food into body mass (feed: meat ratio)
Beef= 7:1
Pork= 5:1
Poultry= 5:1
2. CAFOs- Concentrated Animal Feeding Operation model
Immense scale- “Food animal” population of over 20 billion

Animal Consumption: FEEDLivestock directly uses
only 1.3% of the total
water used in
agriculture
The 7 billion livestock
animals in the United
States consume 5
times as much grain as
is consumed directly
by the entire American
population

produce 130 times as
much excrement as
the entire human

waterways more than
all other industrial
sources combined

IRRIGATION WATER WASTEOnly 4% of US farms use drip or precision irrigation, which are more
efficient
Most irrigated farms use 2-3 times more water than their crops need
And waste between 50-80% of irrigation water through leaks, runoff, and evaporation.
