I know this site well and have dived it for 25 years. The reason corals do not grow close to the big vents is that the sea bed is HOT. There is a healthy and diverse coral reef growing, complete with a complement of fishes and other marine life with CO2 seeps bubbling through it a few metres from the big hot vents.
This story is pure alarmism, has no scientific merit and convinces me that the "scientists" working there are frauds.
