Writing in july Physics World, British physicist Alan Calvert
calculated that the animals eaten by people produce 21 per cent of the
carbon dioxide that can be attributed to human activity.
Where can I find this article? I'd like to read it but there's no trace of
it on Physics World web site.
Anybody can help?

Thanks

Aldo

The nearest I got was that it was in the July 2005 edition of Physics World:

In a section called "Lateral thoughts" and entitled "A radical approach
to Kyoto" Your library may have a copy?

I did note that his name is Alan Calverd.

Cut global warming by becoming vegetarian
Global warming could be controlled if we all became vegetarians and
stopped eating meat. That's the view of British physicist Alan Calverd,
who thinks that giving up pork chops, lamb cutlets and chicken burgers
would do more for the environment than burning less oil and gas.

Writing in this month's Physics World, Calvert calculates that the
animals we eat emit 21% of all the carbon dioxide that can be attributed
to human activity. We could therefore slash man-made emissions of carbon
dioxide simply by abolishing all livestock. Moreover, there would be no
adverse effects to health and it would be an experiment that we could
abandon at any stage. "Worldwide reduction of meat production in the
pursuit of the targets set in the Kyoto treaty seems to carry fewer
political unknowns than cutting our consumption of fossil fuels," he says.

GO VEGGIE TO SAVE THE WORLD, SAYS BOFFIN

A scientist has claimed that if mankind turned vegetarian, it would do
more to cut greenhouse gas emissions than any measures to reduce fossil
fuel use.

Alan Calverd stresses he is not a vegetarian himself , nor is he
convinced that CO2 emissions are entirely responsible for climate
change, but he argues that livestock reared to be eaten produce 21 per
cent of the carbon dioxide attributed to humans.

He says vegetarianism has no adverse health effects and his proposal
required no new technology.

And he points out that scrapping livestock farming would free up huge
areas of farmland which could be used to produce biofuels to further cut
C02 emissions.

"A worldwide reduction of meat production in the pursuit of the targets
set in the Kyoto treaty seems to carry fewer political unknowns than
cutting our consumption of fossil fuels," he says. "It also appears to
offer genuine benefits.

"Moreover, it is a simple reversible experiment that can be initiated by
redirecting agricultural policies and subsidies, monitored in real time,
and abandoned at any stage."

He adds that it takes about 60 per cent less land to produce a given
quantity of fat and protein from plants than from animals, and without
livestock production, the world would be in food surplus.

It seems that livestock are a significant contributor to CO2 emissions.
Does anyone know
if wild animals or grass fed cattle are an equally significant
contributor or whether breeding
or unnatural diets are responsible?
