A research expedition recently set sail from Chicago to search for a Great Lakes garbage patch.
So-called "garbage patches" or islands are actually collections of tiny plastic particles that are choking up regions of the world’s oceans. The expedition has been testing the waters of Lakes Huron and Michigan for a similar phenomenon.
I met up with expedition organizer Asta Mail at a marina in downtown Chicago. It’s a hot day, and a street vendor immediately offers us bottled water.
Mail points down at a plastic bottle in Lake Michigan. It’s pretty easy plastic hunting.
