“16 billion pounds of plastic ends up in the ocean each year. And that’s just the tip of the iceberg,” reads the June 2018 cover of National Geographic. The text is set upon Mexican artist Jorge Gamboa’s clever, captivating image (titled “Iceberg Plástico,” and winner of Bolivia’s Biennial of Poster in 2017) of an iceberg-resembling plastic bag. Aside from the fact that it’s a magazine cover worth discussing—in an age when print’s place is ever under question—the cover draws further attention to the dangers of plastic and the damage upon our oceans. Radical action is required—and Nat Geo’s “Planet or Plastic?” initiative is just the tip of an iceberg of activity necessary for change.
