Interesting you post this. There was an episode of a fictional tv show a while ago and they were dealing with the plastic floating in the ocean. I thought it was just a plot device. I was indeed surprised to find out a couple of months later that the floating mass of plastic was indeed real. It is scary the amount of stuff we are introducing into the environment. In a similar fashion, I read an article the other day that they have begun to find amount of opiates in mussels off the Pacific coast. The treated wastewater doesn't remove opiates and the ones that humans are expelling are ending up in the ocean life. Pretty scary!
