The Ocean Has Polished Our Broken Glass And Turned Into Treasure
Much of the glass humans have broken and thrown away throughout history has ended up in the ocean. Luckily, unlike plastic, glass is a natural material made out of sand, that eventually turns back into sand once it has eroded into tiny enough pieces. Before it breaks all the way back down into sand, it is tumbled by the ocean into these dazzling little stones called “sea glass.”
Almost all of the glass that humans have used and thrown away has ended up in the ocean (if it wasn't recycled). Even though this sounds bad for polluting the ocean, it's much less worrisome than other polluters such as plastic. Glass is made out of natural material, sand, and it turned back into the sand after it erodes into tiny pieces. However, before the glass breaks down into the tiny sand, it is plunged over in the ocean into small stones called sea glass. There are entire beaches filled with sea glass located in Scotland, the Isle of Man, Mexico, northern England, Hawaii, Italy, Australia, Nova Scotia, Puerto Rico, Bermuda, the United States, and southern Spain.
