> The microplastic becomes nano plastic, which breaks and becomes picoplastic which breaks and becomes femtoplastic and so on. This cannot be true. Atoms are nanometer sized, so breaking down particles into pico- and femto-plastics would involve nuclear reactions that I feel reasonably safe asserting do not occur naturally. If they did they would change the chemical structure of the products into something no longer plastic (and in fact no longer matter of the form we're familiar).
