> Biodegradable plastics that have not fully degraded are disposed of in the oceans by waste management facilities with the assumption that the plastics will eventually break down in a short amount of time. However, the ocean is not optimal for biodegradation, as the process favors warm environments with an abundance of microorganisms and oxygen. Remaining microfibers that have not undergone biodegradation can cause harm to marine life.[62]
Will I need to pull up a dictionary in my next comment because you'll still pretend not to understand?
> Biodegradable simply means it breaks down into small pieces that you cannot see anymore. They're still there.
The first paragraph you quote just says that some companies claim that materials that aren’t biodegradable in any meaningful way are biodegradable.
The second paragraph you quote just says that some companies release the material into the ocean before it has finished degrading.
