The flames of fear erupted again a year later when cornell university entomologist john losey and his colleagues reported that they had fed milkweed leaves dusted with bt corn pollen to monarch butterfly larvae in the lab and that those larvae too had died . that was the straw that broke the camel ' s back says david pimentel also an entomologist at cornell 一年之后，美國康乃爾大學的昆蟲學者洛西等人提出報告，他們以沾有bt玉米花粉粒的馬利筋葉喂食大樺斑蝶幼蟲，結果那些幼蟲都死了。疑懼之火再度燃起。 “這是壓垮駱駝的那根稻草。 ”
So researchers have headed into nature themselves , measuring the toxin in pollen from plots of gm corn , estimating how much of it drifts onto plants such as milkweed and , finally , determining the exposure of butterfly and moth larvae to the protein 因此研究人員親下田野，到栽種基因改造作物的玉米田里測量花粉中的毒素，估計有多少毒素會飄落到馬利筋之類的植物上，最后還需確定蛾、蝶幼蟲的毒素接觸量。
“ the birdlike gestures are worn away to ? a mere picking and pluck her way between the ? tire rims and the sunflowers , between coke bottles and milkweed , among all the waste and beauty of the world ? ? which is ? what she herself was 那鳥兒般輕盈的姿態如今只剩下撲朔著啄食，撲朔著尋找出路于車輪之間，與葵花簇里，與可樂瓶子堆上，與野草叢中，與世界所有的污垢和美麗當中? ?她自己也正是美麗與污垢的化身。

Recent studies of milkweed plants in and around the cornfields of maryland nebraska and ontario report far lower levels of bt pollen ranging from just six to 78 grains of bt corn pollen per square centimeter of milkweed leaf surface 最近在美國馬里蘭州內布拉斯加州和加拿大安大略省的玉米田所作的研究發現，不管在田里或附近，馬利筋葉片上的玉米花粉粒更少，每平方公分只有6 78顆。
What is toxic the epa estimates that the insects face no observable harm when consuming milkweed leaves laden with up to 150 corn pollen grains per square centimeter of leaf surface 環保署估計，即使馬利筋葉片上每平方公分有高達150顆的玉米花粉，昆蟲食用后也沒有明顯的危害。
Many of species of milkweed are among the most dangerous of poisonous plants , while others have little , if any , toxicity 參考譯文：人類不是擁有智力的唯一物種，高等動物同樣也擁有相當出色的問題解決能力。
