I said that coral rarely exists below 30 meters - and that was in contrast to the OP who said that "most corals live in the deep sea." As for research, beyond the scuba mention I also provided a citation from a reputable organization whose mission is to preserve coral. But in any case you're missing the main point: that the OP is conflating the diverse fauna found around warm-water tropical reefs with sea life found in in colder waters. As I said, there are plenty of reasons to oppose deep sea trawling and I hope the ban is successful. But an infographic that implies that there are colorful Finding-Nemo-esque reefs a kilometer down with "roads, hospitals, kindergartens, dorms" doesn't help. It just makes supporters of the ban look naive.
