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

Animal rights and animal welfare

Human health

World hunger / environment

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).

Input / Output: 1 out of 7 calories converted to meat, what happens with the rest?

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

Environment: Climate, water, erosion, land consumption, ...

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!

Environment: Climate change (2)

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”!

climate-costs.html

Fire clearance of rainforestsPastures for cattle

Feed monocultures (85% of global soy harvest as animal feed)

Environment: Rainforest destruction

� CO2-emissions due to fire clearances

� or later: agricultural areas prevent that woods can function as

CO2-sink (CO2-“sponge”)

Environment: Excrements

Manure – water pollution worldwide

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

nutrition

The biomass of all farm animals exceeds the mass of all wild vertebrates on land by a factor of 20!! Source: V. Smil The Earth‘s Biosphere

Food waste during the production of animal based food

�Animal derived foods: Food chain with 3 (plant � animal � human) instead of 2 elements (plant � human) => inefficient

� > 10 plant calories for 1 calorie of beef

� > 5 plant calories für 1 calorie of pork

� > 3 plant calories für 1 calorie of poultry

1/3 of world harvest (soy + cereals) converted to excrements (with an upward tendency) !!

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).

Livestock and the cultivation of feed require:

= almost 80% of total global agricultural land (cropland plus pastures)

= 30% of total land surface of the earth

= 2/3 OF ALL areas used by humans globally

Source: FAO, 2006; Goodland R. et al,1999

Short food chain plant � human could release enormous areas globally: Possibilities to use these:

�Regrowing vegetation could absorb huge amounts of CO2 from the atmosphere (see slides earlier, interdisciplinary study NL): Massive contribution to climate stabilisation

Massive contribution to climate stabilisation

�Growing of maize for renewable plastic alternatives without causing a global food crisis

�Photovoltaics for energy production, maybe even biofuels would make sense again

Health: What means ...

vegetarian: No meat, no fish, but milk and dairy products and eggs.

vegan: no animal products

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!

of ears!

Maybe at least meat is healthy ... ?

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!

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

Adventists study, studies of the ADA, Uni Gießen,

Bundesgesundheitsamt Berlin, u.v.m.)

Colon Cancer (American Cancer Society, Univ.

Oxford, Univ. San Diego, Krebsforschungszentrum

Heidelberg), breast cancer (Harvard Medical School), prostate cancer (PCRM, Washington DC), gastric cancers (EPIC)

Health – “meat sicknesses” (2)

Osteoporosis (!) (UC San Francisco, USDA-ARS)

Multiple sclerosis (CHRU Grenoble)

Gallstones

Type 2 diabetes

Obesity
