The problem is we don't see the problem.
Because coral reefs sit below the water line, when they start to disintegrate (from pollution, overfishing, climate change, ocean acidification ... the list is long) most of us wouldn't notice. Or — and here's an irony — the more we notice, the more they disintegrate.
Some coral reefs are so overvisited, they are harmed by our attention.
What to do? Well, this is where the sculptors and weavers come in.
