We use it to pack our food and store our goods. Our clothes, vehicles and even homes are made out of it. Plastic is so common that we take it for granted and see it almost like a natural substance when throwing it away.
However, there is a place where every piece of waste eventually gets to, and that's the sea. Plastic contamination in the oceans is at such levels that bits and pieces of it turn up even at the remotest regions, and it is scarcely possible to find a sea animal which hasn't got at least a single piece of plastic in its body.
