This post summarises some key statistics and information on the case for vegan organic.


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 livestock sector accounts for 18% of global greenhouse gas emissions – more than transport, which emits 13.5%.

Grain fed to animals worldwide:

The world output of grain for animal feed is 614,000,000 tonnes
(International Feed Industry Federation website November 2009)
This represents 90kg of grain for every one of the 6,787,900,000 people in the world.

Soya Imports

2,600,000 tonnes of soya were imported into UK in 2008 (and this figure is rising).
(Royal Society / Guardian 16.10.09)
90+% of this is  used as animal feed.

Land needed to grow potatoes as opposed to producing beef

Beef = 8173 m2 land per person per year
Potatoes = 274 m2 land per person per year

Comparative areas of land needed to grow 1 kg of food products

Beef = 20.9 sq m
Pork = 8.9 sq m
Eggs = 3.55 sq m
Vegetables = 0.3 sq m
(The Times, 27 October 2009)

Livestock take up 26% of Earth’s ice-free land and animal feed occupies one-third of global cropland.

Successful Stockfree Farming

Iain Tolhurst of Tolhurst Organics in Berkshire supplies 400 boxes of stockfree organic produce a week to local customers, with a carbon footprint of just 8 tonnes a year, equivalent to that of an average household.

Changing landscape in upland areas of UK:

“What we now have is a cultural landscape created by the interplay of terrain, wildlife, and human use over the centuries.  Would it be a disaster if, following the sad loss of many hefted flocks, farmers decided not to re-stock?  The ecosystems .. would slowly begin to reclaim their ancient realm… it is customary to attack such embryonic woodland as ‘scrub’, but it is nonetheless rich in birds and insects and is high forest in the making.”
Sir Martin Holdgate, former UK government chief scientist, Director of the World Conservation Union.


Policies that reduce greenhouse gas emissions could also substantially reduce obesity, diabetes, heart disease, cancer, road deaths and injuries, and air pollution.

“Cancer incidence in British vegetarians.” Key et al. (2009) British Journal of Cancer. 2009. Volume 101 Issue 1

Vegetarians are 12 per cent less likely to develop cancer than meat eaters, according to new research published in the British Journal of Cancer* in July 2009.

In a study of more than 61,000 people, Cancer Research UK scientists from Oxford followed meat eaters and vegetarians for over 12 years, during which 3,350 of the participants were diagnosed with cancer.

They found that the risk of being diagnosed with cancers of the stomach, bladder and blood** was lower in vegetarians than in meat eaters.

The most striking difference was in cancers of the blood including leukaemia, multiple myeloma and non-Hodgkin lymphoma. The risk of these diseases was 45 per cent lower in vegetarians than in meat eaters.

Professor Tim Key, study author from the Cancer Research UK Epidemiology Unit at Oxford University, said: “Our large study looking at cancer risk in vegetarians found the likelihood of people developing some cancers is lower among vegetarians than among people who eat meat. In particular vegetarians were much less likely to develop cancers of the blood which include leukaemia and non-Hodgkin lymphoma. More research is needed to substantiate these results and to look for reasons for the differences.”

The study looked at 20 different types of cancers. The differences in risks between vegetarians and meat eaters were independent of other lifestyle behaviours including smoking, alcohol intake and obesity which also affect the chance of developing cancer

Danger of diseases transferrable from livestock to humans

A major study published in February 2005 reconfirmed the link between meat consumption and heart problems. The study, which was published in the American Journal of Epidemiology, concluded that among the 29,000 participants, those who ate the most meat were also at the greatest risk for heart disease.
