1. Plastic

Invented in 1855 by ingenious Alexander Parks and revealed at London's Great International Exhibition in London in 1862. Parks combined natural materials, like chewing gum and shellac, with chemically modified rubber, collagen, and nitrocellulose to create Parkesine which eventually grew into today's plastic. Parkesine gradually replaced wood, stone, horn, bone, leather, paper, metal, glass, and ceramic because of it's infinite indestructiblity. Unfortunately, Parks didn't consider the environmental ramifications while in his lab which lead to today's increase in cancers, toxic waste, and even the Great Pacific Garbage Patch, (or Pacific Trash Vortex) an island comprised of plastic and junk approximately the size of Texas, located in the North Pacific Ocean.
