Solar/UV radiation on floating plastic degrades the polymers rather quickly.
Then the other side of the equation is critters adhere to plastic and their weight eventually causes the plastic to sink. You see wood in the ocean just covered with masses of barnacles, which would sink a small piece of plastic quickly.
Most plastics are also not very reactive in the quick digestion systems of fish, so I suspect that much of the small particles simply pass through quickly with no effect on the fish.
A lot of bogus arguements are "floating around" out there.
