Skip that third helping of roast beef, save the planet and do
your heart a favor at the same time. That’s the advice of Alan
Dangour of the London School of Hygiene and Tropical Medicine and colleagues who
(47) the livestock industry’s potential to help the UK
reduce its carbon emissions to half of 1990 levels by 2030, and the knock-on
effect on the nation’s health. They found that the industry
could reduce its emissions, but only if the livestock the UK produces, and the
meat the nation (48) , drops by 30 per cent. Farms must also
optimize(最优化) their energy (49) by, for example,
capturing carbon in animal waste. The health pay-off would be
(50) : 18,000 fewer people would die prematurely in the UK
each year from heart attceks--a(n) (51) of 17 per cent--as
they would eat less of the fats found in meat. The effect would
not be limited to rich nations. The team found that Brazil could (52)
the same health benefits. "We’re not saying go vegetarian, we’re
saying reduce how much livestock produce you consume," says Dangour. The savings
could be (53) higher if reduced death rates from cancer and
obesity had been included,he adds. Agronomist(农艺学家)
Kenneth Cassman of the University of Nebraska warns that cutting production in
one region can (54) it elsewhere, causing a rise in global
emissions. "Reducing production of livestock products in a developed country
like the UK does little to influence global (55) in
production and consumption where most of the increase in demand between now and
2050 will come from (56) countries," he says.
