Meat is crucial for feeding the planet, leading scientists have said, as they warned it is not more environmentally-friendly to go vegan (素食).
Prof. Geoff Simm, Director of Global Academy Agriculture and Food Security at the University of Edinburgh, said, "I think livestock (家畜) farmers do feel they are being demonized (妖魔化)." Often the argument is made that going vegan would minimize land use, but the modelling studies that have been done demonstrate that's not the case. We feel that while livestock production has a range of economic, social and environmental costs and benefits, 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 bioavailable micronutrients (微量营养素), even small amounts of animal-sourced food have a really important effect on the development of children, in the developing world on their cognitive and physical development and they are really important.
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 which grow faster and eat less, which could further reduce the sector's carbon footprint by reducing the amount of methane (甲烷) released by cows.
Prof. Coffey said that the difference in methane emissions from best and worst cattle was about 30 percent and that if all UK farmers used the most efficient animals this could reduce carbon emissions by nearly a third. But 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. Prof. Coffey said that 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."
