巴拿马病威胁香蕉生存

（单词翻译:单击）

The most popular fruit in the world - bananas - may be about to be wiped out by an invisible killer1 bug2.

一种无形的致死性病菌或许马上就要把香蕉——这种世界上最受欢迎的水果——“赶尽杀绝”了。
 
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 essentially3 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 dormant4, waiting to strike, for up to 30 years.
 
And now it's back with a new global epidemic5.
