Why you shouldn't throw trash in the ocean?

"When garbage is thrown in the ocean it affects more than just the water." says Dr.Carson Fish, birds, and other marine life are affected in many ways. They often mistake garbage for food and are either poisoned or choked. Purple Petteca fish are now extinct due to trash.

I was doing a project on trash in the ocean and used this question. I tried to look up the fish (Purple Petteca) and there is no such thing as a Purple Petteca. Plus, there is no citation and no first name for the supposed "Dr. Carson". So in a conclusion, I WOULD LIKE TO CALL THE REPLY ABOVE A HOAX!
