I was talking to a fellow TPT'er about peat and she mentioned that peat, contrary to public perception, is not renewable (in fact, its much closer to a fossil fuel) and is not harvested sustainably.

That brought the conversation to crushed coral. I know its made of coral skeletons, but where does it generally come from? Harvested? Farmed? Collected?

If anyone's got thoughts on sustainability in this hobby, I'd love to hear them.
