If a Piece of Plastic Waste Is Not Recycled and It

If a piece of plastic waste is not recycled and it doesn't make its way to a landfill or waterway (river, lake, ocean, stream, etc.) , what is its most likely fate? Assume that it is disposed of and not left on the side of a road or carelessly discarded.

A) It will break down into small enough pieces that are not visible to the naked eye.
B) It will be incinerated.
C) It will be put outside so that the sun can melt it.
D) It will be stored until future generations come up with a way to re-use it more efficiently than present methods allow.
