ArkadiusBear posted this photo to Reddit, saying:
This thing is 40 years old. It looks like it was thrown away yesterday. When you throw away plastic, it will basically never go away, ever. IF it breaks down, it breaks down into smaller and smaller micro plastic beads. It may even end up back on your plate some day when ingested by fish.
Again, this thing is 40 years old, and it will look almost the same in another 40 years. In fact, some types plastic trash can take up to 450(!) years to decompose.
This piece of plastic, thrown into the sea in 1976, still hasn't degraded at all
