Green Food Choice May Not Be So Green
素食不足于减低温室效应
ScienceDaily (Apr. 1, 2010)— If everyone became vegan and so ate only fruit and vegetables, thenthe reduction in greenhouse emissions for the whole of food consumptionwould be a mere 7%. The widespread adoption of vegetarianism would haveeven less impact, while organic food production actually leads to a netincrease in greenhouse gas emissions. Those are the conclusions of aresearch paper published in the journal Progress in Industrial Ecology.
如果全世界人口成为素食者, 食物所产生的温室气体只会降低7%。有机食物反而会增加温室气体。 以上结论出至于登在 Progress in Industrial Ecology 的研究报告.
Helmi Risku-Norja and Sirpa Kurppa of MTT Agrifood Research Finland,working with Juha Helenius of the Department of Agricultural Sciences,University of Helsinki, have determined that the cultivation of soilfor whatever purpose, whether growing crops or raising livestock is theprimary source of greenhouse gas emissions in food production, notfertiliser production, animal husbandry, nor agricultural energyrequirements.
Helmi Risku-Norja 和 Sirpa Kurppa of MTT Agrifood Research Finland, 与 Juha Helenius of the Department of Agricultural Sciences,University of Helsinki 发现土染的耕耘是温室气体的主要来源，无论是种植农物或培养动物。 并不是肥料制作, 饲养动物或农产能源。
The team explains that for current average food consumption, inFinland, emissions from soil represent 62% of the total emissions.Greenhouses gases released by cows and sheep account for 24%, andenergy consumption and fertiliser manufacture about 8% each. Thegreenhouse emissions performance for extensive organic production ispoor, they explain, despite this approach to farming being consideredthe "green" option, the lower efficiency requires the cultivation ofgreater areas of soil, which counteracts many of the benefits.
研究团指出在芬兰的食物供应中, 62%的温室气体来自土染。 其中动物饲养产生24%, 肥料制作和农产能源各8%. (62-24-8-8=22, 耕种农作物产生22%)
大型的农业活动对减少温室气体的贡献低落, 虽然农业活动看起来很"绿化"，其实大型的农业活动所需的大量土地抵消了他大步分的益处。
Reducing greenhouse gas emissions through food consumption wouldrequire large-scale changes among the entire population, the teampoints out. They suggest that rather than stressing the impact of anindividual citizen's dietary choices, we should be paying moreattention to social learning and to the notion of working towards foodsustainability and security. In general, sustainable consumption mightbe possible by introducing services to substitute for materialconsumption. Although food itself cannot be substituted, a lot can bedone at the household level to improve sustainability of foodprovisioning and reduce food wastage.
以改变饮食来减少温室气体，需要全球人民的配合。 与其改变个人的饮食观念, 我们更应该教育大众有关食物持久性和保安知识。 我们无法持久或代替食物, 不过家户可以提升食物保存方法和减低食物浪费。
"There is a pressing need to design effective policy measures," saysRisku-Norja. "Consumer information is important from the viewpoint offood and sustainability education, leading eventually to adopting moresustainable lifestyles in the coming generations," the team concludes.
Risku-Norja 说我们必须提出更有效的政策。食物持久知识对消费者是非常重要的教育, 未来可以带来更有可持续性的生活方式。
简单说： 不管你是吃肉或素, 最重要是要懂得如何保存食物和不浪费食物。
