Bottom of the Great Blue Hole

Off the coast of Belize, there is a large sinkhole known as the Great Blue Hole. Explorers recently reached the bottom of this sinkhole and made some interesting discoveries. They found new mineral icicles, dead mollusks, and plastic bottles. To make these discoveries, the scientists used sound waves to get a feel for sizes and shapes of objects in this sinkhole. With their discovery of multiple plastic bottles, it is safe to assume that plastic is a big concern for the planet. Their findings are being featured in an upcoming documentary that will be released in the spring.
