In 1997, Charles J. Moore got off-track while sailing from Hawaii back to California, and he “discovered” waters that appeared like plastic soup. Nowadays this is called the “Great Pacific Garbage Patch”.  In this Ted Talk he quickly explains some of his research and his worry about our throw-away culture, link. 

He continues to work today on plastic pollution research, and raising awareness in particular about microplastics.

The same thing happens in our Ocean and our atmosphere, causing currents to move in a circular motion.
