(2015 •廣州) Most of us probably live without vegetables,but a world without chocolate? Now that would be hard!According to chocolate makers,it could happen if we don't act soon.
There are two main causes of the chocolate shortage—chocolate’s growing popularity and less production of cocoa,the plant from which chocolate is made. With more and more people inIndiaand Chinaloving chocolate,not much can be done about the first cause.
Therefore,the only thing we can do is to increase cocoa production. However,new plant diseases and little rain inIvory Coastand Ghana,the world’s largest producers,have reduced cocoa production by 40 percent in the past 10 years. What’s worse,many cocoa farmers in Africa and other cocoaproducing countries likeIndonesiaandVenezuelaare changing to easier-to-grow crops such as corn or rubber. This way,the farmers can make more money.
To prevent more farmers from changing,researchers at the newly opened International Cocoa Control Centre,in theUK,are trying to create new cocoa plants that are stronger and faster growing.
But first they must make sure the new plants are safe to grow. This takes a long time.
First,each new plant is stored at the Control Centre for six months to make sure it is healthy. It is then planted in the Centre’s fields,studied and tested for another two years. Only after scientists are certain that theyJre diseasefree,will the plants be sent to farmers in West Africa or wherever else they are needed.
To create new stronger types of cocoa,scientists at the Centre are combining the best parts from different cocoa plants. Though the world is facing a serious chocolate shortage,there is now hope!
