I also love this comment from one of the readers:
Who really cares about coral reefs? What good do they do for us?
And it wasn't sarcastic - goes to show that... well, people like this exist .
If you want to somehow visualise the corruption of our society, you don't need to, these corals do a good job . There's nothing good in these black ooze-covered branches that once used to be homes of thousands of species from microbes to sharks. All sea life starts from corals and planktons.
