Future Food – nutrition (almost) without livestock?

Global consequences of our nutritional habits & livestock
-The consequences of the worldwide production of 65 billion farm animals per year on the environment and
climate, global nutrition, animal welfare and human health – and possible alternatives!
Livestock / Consumption of animal products
Global consequences – the major 4:
Environment (incl. climate)
World nutrition / world hunger

Meat = lengthened food chain => requires 5-15 times more areas, plants, water etc. to feed

water etc. to feed humans (Exception: Pure pasture management of ruminants, which on the other hand requires huge areas, causes much of the methane-issues, furthermore only small share of global production).
World hunger / environment
Input / Output: 1 out of 7 calories converted to meat, what happens with the rest?

Global consequences of our nutritional habits & livestock
Metabolic losses inevitable (compare humans), Bread example, livestock first of all an efficient production of excrements, meat as „side product“, by far biggest waste of food globally, 1/3 of world harvest (cereals+soya) converted to excrements!
« The livestock sector emerges as one of the top two or three most significant contributors to the most serious environmental problems, at every scale from local to global. The findings of this report suggest that it should be a major policy focus when dealing with problems of land degradation, climate change and air pollution, water shortage and water pollution and loss of biodiversity. Livestock’s contribution to environmental problems is on a massive scale and its potential contribution to their solution is equally large. The impact is so

potential contribution to their solution is equally large. The impact is so significant that it needs to be addressed with urgency. Major redutions in impact could be achieved at reasonable cost »
Livestock’s Long Shadow, FAO 2006
Land consumption, water consumption, water pollution, rainforest destruction
Climate, loss of biodiversity, soil erosion, air pollution
According to the FAO, the livestock-sector is responsible for 18% of global greenhouse gas emissions – more than total worldwide traffic
(aeroplanes, cars, trucks, trains, ...):
Environment: Climate change (1)

(aeroplanes, cars, trucks, trains, ...): Methane (CH4): digestion of ruminants, …
Nitrous Oxide (N2O): fertilizer, manure, …
Carbon dioxide (CO2): fire clearing of
rainforests etc.
Interdisciplinary Study NL: Worldwide Reduction (definition see paper) of consumption of animal products saves
20 000 000 000 000 US$ (=50%)
of climate stabilisation costs (Aim: GHG concentration levels 2050 same as today) - enough to build 130 million one-family houses at the cost of US$ 150 000 each - new houses for whole Europe!

cost of US$ 150 000 each - new houses for whole Europe!
<
Reasons:
1. Saving of the CO2, N2O and CH4-emissions from
livestock,
2. Vastly reduced land consumption, partly regrowing
forests, bushes => huge CO2-sink due to regrowing forests
=> climate protection “almost for free”!

Fire clearance of rainforestsPastures for cattle
Feed monocultures (85% of global soy harvest as animal feed)
Environment: Rainforest destruction

Enormous amounts, more than humans produce - no wonder as
farm animal population > 25 billion (> 3 times number of humans)
and “production” of 65 billion farm animals per year.
World hunger
Of 7 billion humans800 000 000 suffer from hunger, among these are 200 000 000 children.
25 000 people die from malnutrition each day.

FAO-Report “Crop Prospects and Food Situation” 2008:754 million tons of cereals are fed to farm animals each year (with a yield of
1:7 for calorie-conversion this is a loss of calculated 650 million tons of
cereals for human nutrition) – soy, etc. not yet included
Compare: Due to biofuel production (2nd biggest problem for loss of
calories at croplands) we lose “only” 100 million tons of cereals for human

= almost 80% of total global agricultural land (cropland plus pastures)
= 30% of total land surface of the earth

Health: What means ...
vegetarian: No meat, no fish, but milk and dairy products and eggs.
vegan: no animal products
Kurt Schmidinger – www.futurefood.org

vegan: no animal products at all, i.e. no meat, dairy, eggs, fish, ...
further forms like raw food, macrobiotics, frutarism, ...
Maybe at least meat is healthy ... ?
Vegan instead of ears!

And these are especially important advantages again especially for vegan diets:
De facto all worldwide pandemics of the last decades (bird flu, swine flu, EHEC, BSE, ...) and of the future (...,...,...) from intensive livestock farms:Billions of animals packed together, bad housing, bad immune system, ... => without livestock avoidable!
Antibiotic resistance from intensive livestock farms (“factory farming”)
Health – veggies celebrate!
Kurt Schmidinger – www.futurefood.org
Geophysicist & Food Scientist
Global consequences of our nutritional habits & livestock
Antibiotic resistance from intensive livestock farms (“factory farming”) would be avoidable
Bacterial food poisoning (salmonellosis, E Coli, etc.) mostly a problem with animal products => avoidable
You get far less of these “evils”: Cholesterol, arachidonic acid, purines, saturated fatty acids, also free radicals/ox.stress, ...
You get more of these “good things”: Vitamin C+E, fibres (whole meal) and phytochemiclas (fruits!, vegetables!, antioxidative effects etc.)
Health – “meat sicknesses” (1)
The (high) consumption of animal products is linked to the following sicknesses:
Cardiovascular diseases (Oxford Studies, 7th Day
