Do you know where your plastic goes? To the ocean. Let's put two and two together. You know those plastic "rings" that hold a 6 pack together? When they are thrown away (even though they should be recycled), they go out to the ocean and when fish / dolphins are swimming around, the "rings" get caught around their noses. The dolphins cannot break free, cannot open their mouths to eat, or if the "rings" get to tight, can stop their breathing and they die.
After taking off the "rings" from the 6 pack of soda, beer, ginger ale, etc make sure you cut them apart. Cut the "rings" even if you are going to recycle. Don't take chances.
