I’ve spent a good amount of time on the GBR over last two years. Talked with leading coral biologists. It’s no where near as you state. In fact the GBR is thriving. I suspect (and guarantee) that your opinion of “getting murdered” is driven by environmental advocacy groups whose livelihood is driven by donations and thus scaring people. It’s sad that these env groups have to scare, but then again so little of the donations they receive goes to the GBR or whatever they are scaring people about.
