Re: the USA and most western nations do NOT dump plastic into the oceans
Sorry Bob, but have you seen the sides of the roads and highways these last few decades ?
Plastic bags full of trash are lying there. Sometimes it's just a plastic bag, or an empty plastic bottle.
The truth is, people are pigs. They do not hesitate to throw away anything they decide they don't need any more, and many don't give a damn about where they are when they throw something away.
My favorite example ? Smokers. When they're done with their cigarette, that butt will go flying, be it on the sidewalk or through a car window. Look for a trash can ? Are you kidding me ?
So plastic has got into the oceans not through any government program, obviously, but through the sheer don't-give-a-damn of a large part of the population that goes to the beach and doesn't care what they leave behind when they decide to leave. Some might attempt to look for a trash can, but if it's more than 20 meters away, or if it's already overflowing, fuck it, they'll just leave their trash right there.
Now, obviously, I'm not saying everyone does that, nor am I saying that that is happening on every single road or beach of the world. It has happened enough, though, so that there are several areas in our oceans that are choking with plastic residue.
That would not have happened if everyone was mindful of putting their trash where it belongs : in the bin.
