Question
Listen to a radio program about the Great Barrier Reef in Australia. What is causing the most serious problems to the reef?
Answer
The Coral Reef is particularly sensitive to the climate change and has recorded a mass number of bleaching events. Alarming levels of heats are putting the corals at serious risks. There have been 5 mass bleaching events since 2016 all because of ocean rise temperatures caused by global heating. In the following years they will be reproducing less and in the worst affected areas most of the corals are dying.
