Diet And The Earth
10 kg Grains vs 1 kg Meat The basic concept of meat production (1) The conversion rate of meat production 14 cal Food vs 1 cal Meat Implication(1): meat is a food wastage
the meat production equilibrium Grains + land use + water + energy = Meat + waste Implications (2,3): Meat production is low efficiency usage of resources Meat consumption leads to pollutions The basic concept of meat production(2)
people in 3rd world countries do not have enough to eat. thousands die of malnutrition Every day Implication(1): meat is a food wastage
more than 80% of corn and... more than 95% of oats... are fed to live stock... In the U.S.A. not to hungry people.
not to hungry people 75% of Third World imports of corn, barley, sorghum... are fed to livestock… to produce cheap hamburgers...
The grains and soybeans that are fed to US livestock could feed 1.3 billion people.
The worlds cattle alone consume a quantity of food enough to feed more than the entire human population Resources on Earth are plentiful Resource wastage originates from meat consumption
Implication (2): Meat production is low efficiency usage of resources waterwasted landwasted energywasted
Water It takes more than 25,000 litres of water to produce I kg of beef It takes 200 times more water to produce a kg of beef than to produce a kg of potatoes
Land 260 million acres in the US have been cleared to grow crops to feed livestock. 30% of land in the USA is used as grazing land to feed cattle for slaughter.
Compared to soy production Meat production demands 6~20 times more fossil fuels Energy
Implication (3): Meat consumption leads to pollutions The amount of manure that are produced by farm animals is simply overwhelming
Water contamination, sickness, and death have been occurring in areas where livestock operations are concentrated.
Air Pollution Methane-emitting livestock contribute massively to the Greenhouse Effect and global warming. Ammonia from animal waste contributes to acid rain which kills plants and animals.
1. Biased information + addiction to taste 4.starvation 5. Deforestation + unnecessary resource wastage 7. air, land, water pollution 8. eco-imbalance, climate crises, elevated living expense, compromised health, survival crisis of earthlings 6a. GMO + chemical Fertilizer, pesticides application 6b. Water, land, energy wastage Niche of Meat Consumption from Eco-social perspective 2. Meat consumption surge 3.food shortage
