Hi again,
This from the December 17 edition of the UK-based New Scientist.

Save energy, eat
green
Are you considering switching to more eco-friendly
fuels and means of transportation? You could do more by going vegan, say
two University of Chicago researchers.
Gidon Eshel and Pamela Martin looked at the amount
of fossil fuel used in the cultivation of various foods. This included
the running of agricultural machinery, crop irrigation and the
provision of food for livestock. Other factors considered were the emission
of methane and nitrous oxide gases produced by stock animals and their manure.
They found that the typical US diet, of which
about 28 per cent comes from animal sources, generated the equivalent of
nearly 1.5 tonnes of carbon dioxide per person per year more than a vegan diet
with the same number of calories. By comparison, the difference in annual
emissions from an average saloon car and a hybrid energy-efficient vehicle is
just over a tonne.
However, the eco-friendly meat-eater
needn't rush off and join a vegan commune. The article advises there is an
alternative: eat less-processed animal products and poultry instead of red
meat and thus help reduce greenhouse gases.
