As a result, crown-of-thorns starfish populations can periodically grow unchecked, devastating reefs. For this, parts of reefs are often chopped away to clear a path. 16 Pollution can introduce pathogens. Dredging also releases plumes of suspended sediment, which can settle on coral reefs, damaging them by starving them of food and sunlight.
