Note: Seaweed species such as kelps gives important nursery ecosystem for fisheries and other marine species and save nutrient sources; on the other hand species like planktonic algae, perform a vital role in capturing carbon, producing up to 90% of Earth's oxygen. Understanding these roles offers principles for preservation and continual use. Mechanical dredging of kelp, for instance, destroys the resource and dependent fisheries.
