Meat is crucial for feeding the planet,leading scientists have said,as they warned it is not
more environmentally-friendly to go vegan ()
Prof.Geoff Simm,Director of Global Academy Agriculture and Food Security at the
University of Edinburgh,said,"I think livestock (farmers do feel they are being
demonized(w妖魔化).”Often the argument is made that going vegan would minimize land use,
but the modelling studies demonstrate that's not the case.We feel that while livestock
production has a range of economic,social and environmental costs,the costs have perhaps
been receiving far more attention recently than some of the benefits.Meat has massive social
benefits.It's an important source of dietary protein,energy,highly bio-available micronutrient.
Even small amounts of animal-sourced food have a really important effect on the cognitive and
physical development of children.
Prof.Mike Coffey,from Scotland's Rural College,added,"It's completely unnecessary to
go vegan.If everybody went vegan it would be devastating for the UK environment,animals
bred for food help boost biodiversity."
Researchers are currently attempting to breed more environmentally friendly cattle
growing faster and eating less,which could further reduce the sector's carbon footprint by
reducing the amount of methane (released by cows.Prof.Coffey said the next stage will
be trying to measure the methane given off by different breeds of cattle to find which are the
lowest emitters.Soon shoppers could be able to check meat labels to find out how much
environmental impact their food has had.He added,"My expectation is that at some point in
the near future there will be product labels that relates to the efficiency or carbon impact of the
food."
Professor Andrea Wilson,also of Edinburgh University,said more research was needed
into the impact of veganism(绝对素食主义).She added,,“We know a lot about the livestock
sector because people have looked at it.We actually know very little about the vegan sector.
The danger is we demonize one and jump too quickly to the other."
