Are we sure releasing new engineered corals is a good idea? I get the whole replacement, thing and protecting biodiversity that the corals help protect. However, this could be bad long term, what if there's a blight that affects that specific coral. What if there's something we don't realize about the distribution of species of coral that is important to the overall ecosystem.
