Australia’s Great Barrier Reef will lose most of its coral cover by 2050 and, at worst, the world’s largest coral system could collapse by 2100 because of global warming, a study recently said.

     The study by Queensland University’s Center for Marine Studies, commissioned (委托) by the Worldwide Fund for Nature, said that the destruction of coral on the Great Barrier Reef was unavoidable due to global warming, regardless of what actions were taken now. “Under the worst-case scenario, coral populations will collapse by 2100 and the reestablishment of coral reefs will be highly unlikely over the following 200-500 years,” said the report entitled “Implications (可能的影响) of Climate Change for Australia’s Great Barrier Reef.”

     The Great Barrier Reef is the world’s largest living reef formation stretching 2,000 km north to south along Australia’s northeast coast. “Only if global average temperature change is kept to below two degrees Celsius can the Reef have any change of recovering from the predicted damage,” the report said. Coral has a narrow comfort zone and is highly stressed by a temperature rise of less than one degree Celsius. Water temperature rises of less than one degree coincided (同时发生) with the world’s worst recorded coral bleaching (颜色变淡) period in 1988. The warmer water forces out the algae (海藻) that give coral its color and, if all are lost, the coral dies and the reef will die out. In 1988, 16 percent of the world’s coral died, with 46 percent of the Indian Ocean coral destroyed.

     Scientists express water temperatures to rise this century by between two and six degrees Celsius. “There is little to no evidence that corals can adapt fast enough to match even the lower  temperature rise,” said the report. Over-fishing and pollution from coastal farms were also contributing to the destruction of coral on the Great Barrier Reef.

     The Great Barrier Reef supports huge fishing and tourism industries. Even under favorable conditions tourists would only be able to experience real corals in reef “theme parks”.

An interview with a volunteer.

  ___________________

I am a member of our school’s volunteer association. During my freshman(大学一年级新生) year, I was asked to write up a plan for volunteers who assisted patients there. So I visited the hospice (末期病人疗养所) several times. Later, I realized I could do more for the patients and so began volunteering.

  ___________________

When I was a freshman, I was not used to college life. I sometimes felt the hospice was like home. Here, many grannies treated me like their own relative, and I could feel strongly that I was needed. Just shaking hands made them come to life. I not only get great comfort from helping many patients get through the last period of their lives. I also learn a lot from their experiences.

  ___________________

You have to be prepared both mentally and physically. Most people at this hospice are facing death. So you have prepared to be patient and make them happy and relaxed. Also, persistence is needed. After seeing so many people here die, I know that persistence is hard. But you have to remember that you job is to help them feel less pain before death.

   ___________________

Good volunteers have something in common: They regard their job as a career, rather than some task that’s been assigned. They learn to enjoy what they are doing, no matter how boring it is. We have a volunteer who has been with us for more than a year. His job is translating letters from kids we helped. Even when he was busy with his classes, he would take a taxi to our office to pick up the letters. When we asked him why, he told us he enjoyed the kids’ stories and learned a lot from them.

  ___________________

Students are often very enthusiastic and direct. They give us feedback that helps us improve our work. And they value the opportunity we give them to broaden their horizons. However, they are still young and some are not responsible enough. And sometimes, they are lazy and careless.
