Livestocks Long Shadow
|
The way we do meat production in the US contributes to climate change more than our entire transportation network (cars, trucks, trains, planes, etc.)
|
|
|
Lester Brown
|
Scientist studying food production issues
Most scientists are calling for 80% reductions. US has plans for 17%. Can either ride a bicycle and eat steaks, or drive a car and be a vegetarian. World can't sustain both. Advocates high speed rail rather than highways |
|
|
Transportation Solutions That Work
|
Hybrid Car
Electric Car (90% of forces moves car forward vs. current car that loses 90% of energy) Wind Turbines Solar Energy |
|
|
Animal Feed Lots
|
Given massive antibiotics
Clip and break toenails Fed bizarre foods Feed sheep parts to cattle Looking for maximum weight to market |
|
|
Animal Feel Lot Waste
|
Too extreme for earth to handle
Too many animals per acre Have hugse waste holes that leak into water Produce large amounts of methane gas |
|
|
Poultry
|
Huge amounts of waste in water
Bred to be genetically similar One disease can wipe out whole species |
|
|
US Livestock
|
Produce 3 tons waste/American/year
|
|
|
Alternative: Anaerobic Digestion
|
Collect methane from breakdown
Put waste into taks Sell the methane Use the solids as fertilizer Takes time; too slow for our large numbers |
|
|
Corn Utilization in US
|
Poor source for biofuel
Takes as much gas to grow/ship biofuel Used primarily to supplement US farmers Not fit for human consumption Not economical to grow Only produces 15% less greenhouse gas |
|
|
Biodeisel
|
Not cost effective
Resource intensive Crops compete with food production |
|
|
Pesticide Use
|
More toxic since WWII
Runs off into streams, rivers, etc. Increased use in other countries Natural systems unable to break them down Hormone mimics cause cancer |
|
|
Food demand
|
Not enough land to meed the rising demand
Need more efficient crops or a mix of energy solutions |
|
|
Good fuel alternatives
|
Ethanol from sugar cane
Gets 4x the energy out than put in Price is competitive with gas Illegal in US because it competes with oil companies Should NOT cut down rainforest to produce it |
|
|
Jatropha
|
Plant that's easy to grow
Produces nuts giving oil for biofuel when pressed Peplaces nutrients in soil Will work in low soil conditions Cheapeast biofuel made |
|
|
Major changes in food industry
|
Heavy chemical treatments
Grain shortages More starving people Genetically modified organisms Rising food prices Greater fossil fuel use |
|
|
Current Food Industry
|
Integrity of ood has been compromised
Farmers battling giant corporations like Monsanto Genetically modified foodss have pesticides and chemical treatments that cause cancer |
|
|
Western Worlds Food Production
|
Leads to overeating
Is more than required 1800 calories per day Pushed by financial sector for profit Pushed by media to consume highly processed animal based foods |
|
|
Food Production & Climate Change
|
18% of greenhouse gas emitted by livestock
Reduced rainfall & drought in Africa Flooding in Asia |
|
|
Milk
|
Altered by injection of rBGH (recombinant bovine growth hormone)
Causes infection and pus Cows given antibiotics; makes human build up resistance Increase in sterility and cancer |
|
|
Genetically Modified food outcome
|
Damage to immune system
Damage to organs Smaller brains, livers, and testicles Enlarged tissues Atrophy of liver Increase in cancer Changes seen in 10 days (10 human years) |
