If all nations worked together could we make significant strides towards removing existing plastics from the ocean, or is it a lost cause?

Yes, I am well aware and no I don't watch those cartoons. Thanks for the informative response.

I was more interested in cleaning up what is already there, like these giant floating garbage patches. Of course much can and needs to be done to prevent further damage, but I wonder how much we could reverse the damage already done.
