Consider an average deodorant tube. Packaged in a hard plastic case, your deodorant contains lots of tiny plastic components for twist-ability that are not recyclable. This means that out of the all deodorants sold in the U.S. last year, most of them were tossed into the trash, with many of them ending up in the ocean. (Yes, garbage often ends up in sewers, rivers, and the ocean on its way to the landfill.)
The result? Whales with bellies full of plastic, vanishing coral reefs, and a patch of trash three times the size of France floating in the middle of the Pacific Ocean. Plastic waste is so pervasive that it has been found at the furthest depths of the ocean, and as plastic containers break down, tiny plastic fragments invisible to the naked eye (microplastics) end up in waterways and eventually, into the very fish we eat.
