新奇事件簿 牛肉生產(chǎn)破壞環(huán)境

A new study says beef production is very damaging to the environment. It damages the environment around ten times more than the production of pork, lamb, chicken or other farm animals. Scientists said cows need 28 times more land and 11 times more water than pigs, sheep or chickens. They also produce a lot of greenhouse gas after they eat. Compared to food like potatoes, wheat, and rice, beef production needs 160 times more land and produces 11 times more greenhouse gases. The scientists said farming (of livestock and crops) is a major cause of global warming. It causes 15 per cent of all greenhouse gases. About half of this is from livestock.

一項新的研究表明，牛肉生產(chǎn)會嚴重破壞環(huán)境。生產(chǎn)牛肉對環(huán)境造成的破壞程度是生產(chǎn)豬肉、羊肉、雞肉等家畜所造成的破壞程度的十幾倍?？茖W(xué)家稱，飼養(yǎng)牛肉與飼養(yǎng)豬、羊、雞相比，需要28倍多的土地，需要11倍多的水。牛在進食之后，也會產(chǎn)生大量溫室氣體。與土豆、小麥和水稻相比，牛肉生產(chǎn)需要160倍多的土地，并且會產(chǎn)生11倍多的溫室氣體?？茖W(xué)家稱，農(nóng)業(yè)(飼養(yǎng)家畜和種植糧食)是全球變暖的主要原因之一。農(nóng)業(yè)產(chǎn)生的溫室氣體約為所有溫室氣體的15%。其中一半來自于家畜。

One scientist said we could all reduce our carbon footprint by eating less beef. Professor Mark Sutton from the Centre for Ecology and Hydrology in the UK said cutting down on the amount of beef we eat is better for the environment than using the car less. He also said that if we ate less beef, we could use the wheat that farmers give to cows to feed starving people. He said this sounds simple, but many governments would not try to do it. Professor Sutton said: "Governments should consider these messages carefully if they want to improve overall production." He added: "The message for the consumer is even stronger. Avoiding excessive meat consumption, especially beef, is good for the environment."

一位科學(xué)家說，我們可以通過減少牛肉的食用量來降低二氧化碳排放量。來自于英國生態(tài)與水文中心的馬克.薩頓教授，稱降低牛肉食用量對環(huán)境的好處，比降低使用汽車頻率的好處還要大。他還說，如果我們少吃牛肉，我們就可以把農(nóng)民喂給牛的那些小麥救濟那些挨餓的窮人。他說，這聽起來很簡單。但是，大多數(shù)政府不會這樣做。薩頓教授說，如果政府想要提高總產(chǎn)量，那就應(yīng)該考慮一下這些信息。他還說，消費者的信息更加有效。避免過度吃肉，尤其是牛肉，對于環(huán)境有好處。
