In a kelp forest, with kelp more than 3 feet high, some corals won't have enough sunlight to produce the sugars and food they get from photosynthesis. Photosynthesis by the way is a process used by plants and other organisms to convert light energy, normally from the Sun, into chemical energy that can be later released to fuel the organisms' activities.
If temperatures continue to rise, the oceans may become too warm to allow kelp growth; therefore, existing kelp would die and restoration would be next to impossible because young kelp is especially vulnerable.
