Do you like eating bananas? Of course. They taste good and you don't have to wash them before eating. 1. , British scientists say that the fruit may disappear by 2050.
One reason for this is climate change. Scientists at the University of Exeter collected data from 27 countries for 2. study. They found that climate change made growing conditions better in most of these countries. But if it's too hot, they will stop growing. Shouldn't bananas grow more easily if it's hotter outside? In fact, the perfect 3. for growing bananas is between 24℃ and 32℃. If it keeps 4. , ten of the countries, including India, the world's biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may 5. out.
6. danger to bananas is diseases(疾病). Unlike other plants, the bananas we grow come from shoot cuttings but not seeds. This means that all banana plants have the same genotype (基因型). In other words, if a disease is able to kill one plant, it could kill them all. Panama disease, a 7. disease, begins from the soil and spreads quite easily. It has killed 8. of banana plants across South Asia, Africa, the Middle East, and Australia. If one banana plantation gets the disease, it will take 30 years until it is able to grow bananas again.
As a result, we need to do 9. to protect banana plants. First, the governments should try their best to support scientists in finding new ways to protect banana plants from diseases. Second, it's necessary to improve farming practices to make sure banana plants have better growing conditions. For 10. , using more organic fertilizers(有机肥料) can help keep the soil healthy. Also, we may develop new types of bananas that are more resistant to the changing environment.
We hope that bananas will still be around in the future and continue to be a delicious and popular fruit.
