Clearly you have some axe to grind. If you think that you can help restore a reef by tossing bread out then there are probably groups out there that will fund you and let you try it. The ecology of reefs is well-studied, as is what happens when different groups are removed from the ecosystem. These studies have been working very hard to restore the reefs that have been screwed up - and this ranges from patrols to stop illegal fishing to 3D printing reef structures, interconnecting reef blocks, growing corals in nurseries to kick-start reef regeneration, developing drones to automatically identify and kill Crown of Thorns starfish, etc. Different things work in different parts of the world to offset different problems. But if a group can get finding to paint the rocks around a glacier white to slow it melting then someone may fund you to throw out bread. Not all species of fish, or the invertebrates eat bread just as carnivorous animals can't be trained to eat tofu.
