Dexter Should Go Green

I've recently become obsessed with the TV series Dexter. I'm watching it on Netflix and am about halfway through the second season. For those of you that don't watch the show, its a dark but intriguing story about a vigilante seriel killer that is constantly struggling between right and wrong.
HOWEVER, in all of his struggles, and in all of his inner dialogues, he never considers the consequences of dumping his murdered victims in the ocean! He wraps them in trash bags and dumps them over the side of his boat. Not cool Dexter!
