We live in a symbiotic world. We are slowly discovering our interdependent nature.
I found these videos interesting which depict how important Saharan dust is to life in the ocean around South America, and how it leads to the growth of Phytoplankton which is the foundation for much of the life on Earth. The video also discusses the importance of this same airborne dust to the growth of the Amazonian rainforest in distant South America.

The second video provides further information on how the Saharan dusts help to revitalise the green vastness of the Amazon.
