Most plastic is photo-degradable. Left in the sun, it will disintegrate as you saw. [0] Most plastic ends up in a landfill or deep in the water or burred under more plastic where it is not touched by the sun and does not degrade. Plastic on the surface of the ocean breaks into smaller pieces which end up deeper in the sea, and does not degrade further. The ocean is filled with tiny plastic bits.
