Scientists reported that climate change might actually be helping ancient trees thrive(长得健壮). Now there seems to be more positive news—this time about the coral in our oceans whose population has been severely affected in last few decades by rising temperatures, disease and human carelessness.

Coral reefs as you probably know are not just colorful calcium carbonate(钙碳酸盐)structures that provide shelter to a wonderful number of fish, but also a close relationship or partnership between coral polyps(珊瑚虫) and single celled living things called zooxanthellae(虫黄藻). The coral polyps give the zooxanthellae a home and in return the later provide the coral polyps with their vivid color and food. They support each other in a fantastic balance, one that is getting severely damaged by the rising temperatures which are causing the coral polyps to reject their zooxanthellae friends, removing their color and food source.

Scientists estimate the phenomenon of rising temperatures combined with disease has destroyed the coral reef population by more than 80%. It is therefore no wonder that scientists all over the world are looking for solutions to try to restore this all important link to sea life. However, while human efforts like planting the coral again have been somewhat successful, they are not enough to replace all the coral that has been dying due to climate change. That is probably why reports by various researchers about certain types of coral being able to not only survive the changing ocean conditions, but also thrive in it, are being met with such enthusiasm. The most recent findings show that despite higher temperatures the coral reefs seem to be thriving.

These findings are consistent with the lab research conducted by the scientists who tried growing different varieties of coral in waters with higher temperature to see how they would react. They were surprised to discover that most of them survived and some seemed to adapt and grow normally. Encouraged by these and other similar findings, more energetic species have been introduced to see if coral reefs can be restored to their former glory. A program is busy analyzing the world's oceans to find more varieties that can be used for this same purpose．

However, we are not out of the woods yet! Scientists are still not sure how they would introduce these varieties to areas where they are not abundant and more importantly what the consequences would be on the surrounding sea life. Hopefully, the combination of new scientific research and fewer human mistakes will allow our beautiful coral to thrive again!

Dear Mary,

I received your E-mail just now. Don't worry about me. I'm getting well with my research work in the lab. But to my great surprised, you say you will give up learning English. The reason is because you have not done well in it recently and you have lost interests in it. I'm afraid I can't agree with you more. I know it is difficult to learn English, but English is wide used in the world today. It will be a important tool in our future work. Besides, it is becoming more and more important in ours daily life. If you study hard, you would be successful. Do remember that where there is a will, there is a way. I'm looking forward to hear good news from you.
