Commercial fertilizers, which are made by humans, are used to enrich soil for healthier crops. However, erosion may carry the fertilizer chemicals to the oceans. The presence of these chemicals may cause certain kinds of algae to reproduce rapidly. This decreases the amount of oxygen in the water, which can cause organisms that depend on it, like fish, to die.
