Good video. Lots of “coral reef” themed videos around but surprising few that give a well-rounded out explanation of what they actually are (like this one) for the less-aware.

77 Likes for this informative video? Here's another. People should see more of this so they know why they shouldn't disturb/destroy reefs.

Tremendous and well done!

makes me wonder if in fact humans have not built the largest infrastructure. Coral is literally cementing (limestone) and the reefs can get up to a thousand miles long. I don't know what that volume is total, but the only thing I can think of that we have built of that magnitude is the Great Wall, which must be dramatically thinner than the reefs.
