The great barrier reef is growing but most of this growth is to a single species of quick growing Acropora coral species. There is an ongoing boom of crown of thorn starfish, which eat this coral. This coral is also very vulnerable to strong wave action in storms. So at best its now a growing monoculture of coral and at worst between the starfish and the storm waves, it crumbles away. So most of the old growth coral is gone and is not returning along with the reef-dependent animal life CM mentioned.

Human caused climate change is fake. Paying the government more taxes won't fix it. The climate has been changing for longer than we have been around and will keep changing after we are gone.
