I wrote this short story for the National Geographic #PlanetOrPlastic writing contest. My story is written in the format of a epistolary - a series of letters. It follows five people's correspondence to friends and relatives throughout the history of modern plastics use, from the 1946 National Plastics Expo to a time in the near future when plastic and other types of pollution and debris threaten to destroy the Earth's oceans and throw awry the balance of gases in the atmosphere, temperature and weather patterns, and varied marine species' food chains, to a point where there is no chance to turn back. I hope you enjoy my story and that it inspires you to rethink your role in protecting our Earth and its indispensable marine habitats!
