Usually, a great deal of the dust in the plume finishes up sinking in the Atlantic Ocean, in which it feeds little microscopic organisms called plankton. When it reaches land, the inflow of dust can transform the way ecosystems purpose, like by fertilizing the Amazon rainforest. It can also interfere with the development of tropical storms and hurricanes, though it can be unsafe for individuals to breathe in.
