African Dust, Coral Reefs and Human Health

Hundreds of millions of tons of mineral dust are transported thousands of miles through the atmosphere from the Sahara and Sahel of Africa to the Caribbean and the Americas every year.

This video discusses whether African dust is playing a role in coral reef declines throughout the Caribbean region, and if African dust has a negative effect on human health. If so, what processes are involved?
