Earth Category:Atmospheric sciences A dust storm traveling from the Sahara Desert over the Atlantic Ocean Dust in Earth's atmosphere comes from both natural and anthropogenic causes. The process of which dust enters Earth's atmosphere naturally can be attributed to the Aeolian Process where winds erode Earth's surface and consequently carry particles from the ground into the atmosphere via suspension . Where as anthropogenic dust may be due to human activities such as farming and creating air pollutants. The solid dust particulates and atmospheric moisture combined are suspended in the air which are both natural and anthropogenic are referred to as Aerosols . The Sahara Desert is one of the biggest contributors in the creation of atmospheric dust as the winds carry and deposit dust and particulates across the planet.Middleton, N. J., and A. S. Goudie. "Saharan Dust: Sources and Trajectories." Transactions of the Institute of British Geographers26, no. 2 (2001): 165-81. URL Atmospheric dust, both natural and anthropogenic, has also been shown to affect humans as well . One of the biggest contributing factors that the effect atmospheric dust has on humans is health, more specifically respiratory health. Barbados and Trinidad have seen a rise in asthma in their population and one of the speculated causes is an influx of dust being carried over the Atlantic from the Sahara desert. Certain Particulates , or particulate matter PM have lead to health issues among humans such as lung disease and cardiovascular disease.
