Why, pray tell, are we DUMPING plastics in the ocean?
American are having their plastic waste collected by their garbage services and put on container ships. These ships take the waste to be processed at off shore centers in countries where labor is cheap. Many times these processing centers become overwhelmed by the amount of waste they are receiving. For them, the answer to their problem is easy: Take the excess plastic out to the ocean and dump it.
If we were to process our own plastic, we wouldn't have the ocean dumping. In those countries that do, it is because there is no regulation of what they do.
