:::facepalm That's lifted from Crown-of-thorns starfish#Ecological impact on reefs almost word-for-word, except you pluralized algae wrong. It's called "destruction" because it destroys the original hard coral ecosystem. Period. A coral rubble habitat is not a coral reef. Just because grasslands might replace a bulldozed rainforest, doesn't make the bulldozer non-destructive. Whatever philosophical bullshit you might have about the truth of the human condition and the conspiracy against starfish or whatever, I only care about WP:RS. You're arguing for argument's sake and blatantly WP:Wikihounding. The irony never stops. Stop.  †
