據(ju)科(ke)學家指(zhi)出,牛羊等(deng)(deng)反芻動(dong)物通(tong)過打嗝和放(fang)(fang)屁(pi)的(de)(de)(de)方式排(pai)(pai)放(fang)(fang)大(da)(da)量(liang)的(de)(de)(de)甲烷(wan),造成了巨大(da)(da)的(de)(de)(de)污染。據(ju)英國《每(mei)日郵報》9日報道,阿根廷(ting)科(ke)學家在(zai)牛背(bei)上(shang)綁(bang)上(shang)一個塑料(liao)罐,專門收集牛打嗝和放(fang)(fang)屁(pi)排(pai)(pai)出的(de)(de)(de)廢氣(qi)(qi)(qi),供研(yan)究之用。 這(zhe)種新(xin)裝置,由通(tong)向胃部的(de)(de)(de)氣(qi)(qi)(qi)管把氣(qi)(qi)(qi)體(ti)(ti)輸送到綁(bang)在(zai)牛背(bei)上(shang)的(de)(de)(de)紅色氣(qi)(qi)(qi)罐中(zhong)(zhong)。一頭(tou)重550千克的(de)(de)(de)牛可排(pai)(pai)放(fang)(fang)800到1000公升(sheng)的(de)(de)(de)甲烷(wan),那(nei)么阿根廷(ting)三分之一的(de)(de)(de)溫(wen)室氣(qi)(qi)(qi)體(ti)(ti)都要歸咎(jiu)于牛羊。 據(ju)悉,阿根廷(ting)是(shi)世界(jie)最(zui)大(da)(da)的(de)(de)(de)牛肉產商,擁有5500萬(wan)頭(tou)牛。 甲烷(wan)會破壞臭氧(yang)層,導致全球(qiu)(qiu)變暖。而全球(qiu)(qiu)10.5億頭(tou)牛排(pai)(pai)放(fang)(fang)的(de)(de)(de)廢氣(qi)(qi)(qi),甚至超(chao)越了人(ren)類交通(tong)工具,如汽(qi)車、飛機等(deng)(deng)的(de)(de)(de)二氧(yang)化(hua)(hua)碳排(pai)(pai)放(fang)(fang)量(liang)。 目前,科(ke)學家正致力于改(gai)進牛羊反芻系統,尋找減(jian)少牲畜甲烷(wan)排(pai)(pai)放(fang)(fang)量(liang)的(de)(de)(de)辦法(fa)。附:甲烷(wan)與溫(wen)室氣(qi)(qi)(qi)體(ti)(ti) 溫(wen)室氣(qi)(qi)(qi)體(ti)(ti)(Greenhouse Gas,GHG) 溫(wen)室氣(qi)(qi)(qi)體(ti)(ti)包括(kuo)二氧(yang)化(hua)(hua)碳、甲烷(wan)、氧(yang)化(hua)(hua)亞氮等(deng)(deng)。燃(ran)燒化(hua)(hua)石燃(ran)料(liao)、農業(ye)和畜牧業(ye)、垃(la)圾處理等(deng)(deng)等(deng)(deng)都會向大(da)(da)氣(qi)(qi)(qi)中(zhong)(zhong)排(pai)(pai)放(fang)(fang)溫(wen)室氣(qi)(qi)(qi)體(ti)(ti)。 因為地(di)(di)球(qiu)(qiu)紅外線在(zai)向太(tai)空的(de)(de)(de)輻射過程中(zhong)(zhong)被地(di)(di)球(qiu)(qiu)周(zhou)圍(wei)大(da)(da)氣(qi)(qi)(qi)層中(zhong)(zhong)的(de)(de)(de)某些氣(qi)(qi)(qi)體(ti)(ti)或化(hua)(hua)合物吸收才最(zui)終導致全球(qiu)(qiu)溫(wen)度普(pu)遍上(shang)升(sheng),所(suo)以這(zhe)些氣(qi)(qi)(qi)體(ti)(ti)的(de)(de)(de)功(gong)...
