Contrary to the commonly held belief that plastic takes 500 to 1,000 years to decompose, researchers now report that some types of plastic begin to break down in the ocean within one year, releasing potentially toxic bisphenol A (BPA) and other chemicals into the water.
This World Ocean Day, June 08th, let’s remember that BPA has harmful effect not only on our health but on marine ecosystems too. BPA is an estrogen-like endocrine-disrupting chemicals very similar to DES

Plastic does break down when exposed to sunlight.. but the toxicity is nowhere near what ha been put into the ocean through the dumping of nuclear waste.

Yes, there is often worst… but we can easily do our part regarding plastics, BPA and “dumping”…
cheers 🙂
There are other problems that generate these wastes: the amount of marine animals die from these materials in the thousands per year, only in the Pacific. where plastic island grows every day.
