Bottom Line

• Showerheads– 5 - 7 gpm (pre-1980)– 2.5 gpm (1992 – present) – required now– .75 gmp – 2.0 gpm available

• 10 minute shower– 10 min x 5 gallon x 30 days = 1500 gallons– 10 min x 2.5 gallon x 30 days = 750 gallons

• Typical family of 4– 36,000 to 72,000 gallons/year on showers

• Toilets– 4.5 - 7 gallons/flush (pre-1980)– 1.6 gallons/flush (low-flow toilet)– 1.3 gallons/flush (high efficiency toilet (HETs))

• Typical family of 4 – w/ old toilet – 26,000 gal/year– w/ low flow – 11,000 gal/year

more water than plant-based diet;

70% of all available water used in agriculture;• ⅓ current farmland is used to grow crops

that feed animals;

95% of world will be forced to be vegetarian by 2050;

Factoids on Food Production

• 2.2 lbs. hamburger/steak = 5400 gal• 1 lb. of bread = 500 gallons• 8 oz. serving chicken = 330 gallons• 8 oz. serving milk = 48 gallons• Typical Thanksgiving dinner for 6 people =

• Water, energy, emissions, waste, etc. • Restaurants use 5-7x more energy per sq./ft.;• QSRs use 10x more energy;• @ 80% of $10B spent on energy is wasted• $1 reduction in energy costs = $12.50 in sales

Individual Action

• Recycling 1 glass bottle saves enough energy to light a 100-watt light bulb for 4 hours

• Recycling 1 aluminum can will run a computer for 3 hours

• Recycling 1 plastic soft drink bottle will save enough to run a TV for 1.5 hours

• Recycling 5 lbs. of paper will conserve enough water to “offset” the water used in a typical shower
