  12月9日口譯文章:巴拿馬病東山再起,環球香蕉在災難逃

  一種無形的致死性病菌大概立時就要把香蕉——這類天下上最受迎接的生果——“趕盡撲滅”了。

  巴拿馬病(香蕉黃葉病)已讓人們最愛好的香蕉品種消逝不見了,如今又東山再起,以野火般的勢頭囊括環球的香蕉作物。

  題目的關鍵在於香蕉沒有果籽,根本上都是從統一植株克隆而來,是以對疾病的抵禦力極低。

  一項最新的研討告誡稱,假如人類不“連忙”采用行為,這類廣受迎接的黃色生果將會永久消逝。

  “大麥克香蕉”曾是天下上最受迎接的香蕉品種,但於上世紀50年月被巴拿馬病滅盡了。

  源自英國的“卡文迪什香蕉”是以代替大麥克香蕉成為最受迎接的品種,今朝占天下香蕉出口總量的95%。

  但是,這類能經由過程水和泥土流傳、直擊香蕉根系的巴拿馬病,可埋伏高達30年之久,乘機再現。

  如今它果真東山再起,激發了又一場環球香蕉病變。

  殺菌劑對這類致命性真菌病原體無效,化學手腕都無論用。

  它使台灣地域的卡文迪什香蕉全體壞死,如今正在中國大陸、印度尼西亞和馬來西亞等地舒展,鼎力大舉撲滅香蕉作物。

  巴拿馬病已使澳大利亞的香蕉家當大幅縮水,如今又威逼到了菲律賓的香蕉出口。早在19世紀時,澳大利亞香蕉家當就曾毀於此病菌之手。

  2013年以來,約旦、巴基斯坦、黎巴嫩、莫桑比克和阿曼等地也都發明了巴拿馬病的蹤影,可見其影響的遠度和廣度。

  The most popular fruit in the world - bananas - may be about to be wiped out by an invisible killer bug.

  Panama Disease – which has already destroyed the most popular variety of banana – is back and its spreading like wildfire across global crops.

  The problem is, bananas are seedless and are essentially all cloned from exactly the same plant – making them extremely vulnerable to disease.

  A new study has warned the much-loved yellow fruit will be wiped out if we don't take action NOW.

  The Gros Michel banana was once the most popular variety in the world – until it was completely killed off by Panama Disease in the 1950s.

  The Cavendish banana – from the UK – stepped in to replace the Gros Michel and now makes up 95% of all banana exports in the world.

  But Panama Disease – which is transmitted through soil and water and attacks the banana plant's roots – can lay dormant, waiting to strike, for up to 30 years.

  And now it's back with a new global epidemic.

  The deadly fungal pathogen is resistant to fungicide and cannot be controlled chemically.

  It has completely wiped out Cavendish banana crops in Taiwan and is now spreading through the Chinese mainland, Indonesia and Malaysia, decimating crops.

  The bug has "significantly" reduced the banana industry in Australia – which previously lost its bananas to disease in the 19th century – and threatens the entire export trade in the Philippines.

  Since 2013 it has been reported as far and wide as Jordan, Pakistan, Lebanon, Mozambique and Oman.
