[TIME] How Cows(Grass-Fed Only) Could Save …
很久沒看TIME
剛剛看了一下 Jan. 25 2010的那期
看到這個
http://www.time.com/time/magazine/article/0,9171,1953692,00.html
紙本上的標題下的有點太聳動
(網路的標題不一樣)
害得我有點小不高興
紙本的標題是這樣的
Save the Planet:
Eat More Beef
Environmentalists have been giving cows a bad rap in recent years.
Between what bovines eat and what the excrete, cattle production
emits a lot of greenhouse gas. But if fed solely grass,
cows could play a key role in reversing climate change.
其實整篇是在講說
吃牧草的牛
因為不用犧牲大片森林、化肥、農藥來製造穀物
不用穀物運輸的化石燃料
牛吃牧草可以促使草生長速度加快
再加上牛的排泄物配合放牧的牛的踩踏
可以使排泄物進入表土而生成腐植質
做為很好的天然肥料
進而使得草的碳捕捉量上升
所以
吃牧草的牛
不只不會增加碳排放量
還可能減少大氣中的碳
"If you suspend a cow in the air with buckets of grain, then it's a bad guy,
but if you put it where it belongs--on the grass--that cow becomes not just
carbon-neutral but carbon-negative."
"With proper management, pastoralists, ranchers and farmers could achieve
a 2% increase in soil-carbon levels on existing agricultural, grazing and
desert lands over the next two decades."
Some researchers hypothesize that just 1% increase(over, admittedly vast
acreage)could be enough to capture the total equivalent of the world's
greenhouse gas emissions.
文章中的主角
Barbara Damrosch and Eliot Coleman
提到說目前聯合國與世界各國提倡的不吃肉(或少吃肉)：
"The idea that giving up meat is the solution for the world's ill
is ridiculous." said Coleman
"A vegetarian eating tofu made in a factory from soybeans grown in
Brazil is responsible for a lot more CO2 than I am."
不過再怎麼說
這些都是要完全只吃天然牧草的牛才有的效果
在我們沒辦法使美國及世界各地其他的畜牧業大地主
改變現有的生產方式之前
我認為不吃(少吃)牛肉及其他肉類仍是最佳選擇
或許當一個素食者或蔬食者是個權宜之計吧
但在現在的情況下
也不能稱此計為愚蠢荒謬吧?
雖然他們的發現(如果是事實的話)
的確很有價值
我也相信他們本意是好的
有興趣可以跟我借這一期的TIME
