Garbage is also a problem in the environment like plastics in oceans, but the problem is not enough (well run and used) land fills (in Asia) not too many!
50% of the plastic problem in the ocean is discarded fishing nets (generally accepted to be discarded from Asian fishing vessels).

looks more like 10% [0]. but it depends on where in the ocean you're talking about - they float more easily than a lot of plastic, and so are caught the pacific gyre.
