As CO2 concentrations in the air increases, more CO2 will also be dissolved into the oceans. For plants such as seagrasses, this could pose a positive outcome for them because CO2 is necessary for photosynthesis. Unfortunately, with increasing UV radiation, equatorial species will have a greater strain on their overall metabolism. UV-B rays slow down photosynthesis, and plants would need to expend more energy producing protective tissues. Ultimately, this group of seagrasses may face a dilemma where they have higher metabolic needs but lowered abilities to meet those needs.
