Cutting meat production and consumption by 30 percent would help to reduce carbon emissions(排放) and improve health in the most meat-loving nations, scientists said on Wednesday.

Using prediction models, British and Australian researchers  1  that improving efficiency, increasing carbon capture and  2  fossil fuel dependence in farming would not be enough to  3   emissions targets.

But combining these steps  4  a 30 percent reduction in livestock（家畜）  5  in major meat-producing nations and a similar  6  in meat-eating, would lead to "substantial population health benefits" and cut emissions, they said.

The study found that in Britain, a 30 percent  7  intake of animal-source saturated（饱和的） fat by adults would reduce the  8  of premature（过早的） deaths from heart disease by some 17 percent -- equivalent to 18,000 premature deaths reduced in one year.

In Sao Paulo, Brazil, it could mean as  9  as 1,000 premature deaths reduced in a year, they said.

  10  the United Nations Food and Agricultural Organization, 18 percent of all greenhouse gas emissions are from meat production and experts say rising  11  for meat, particularly in countries with growing economies, could  12  livestock production up by 85 percent from 2000 levels  13  2030.

The scientists said global action was needed to maximize the benefits of cutting meat production and  14 , and that the environmental  15  "may apply only in those countries that currently have high production levels."

The study was  16  in The Lancet medical journal as part of a series in climate change and health  17  the Copenhagen global climate summit scheduled next month.

In a second study, British scientists found that increased walking and cycling, and  18  cars, would have a much greater impact on health  19  low-emission vehicles in rich and middle-income countries.

Andrew Haines, director of the London School of Hygiene and Tropical Medicine and head of the research series, said delegates at Copenhagen needed "to understand the potential  20  impacts of their plans."
