I used to think the same thing until I moved to Arizona. There are different levels of degradation- biodegrade vs photodegrade; plastics, in the open, photodegrade. especially when exposed to light/heat (like the plastic bags holding my potting soil, and the plastics that are part of my automobile, all have exhibited photodegradation, meaning they break into bits. Are they safely ingestable for me or other creatures? No. The 'thousands' of years to degrade is in landfills, where things are sequestered specifically to NOT break down, polluting groundwater, air, soil, etc.

This is fascinating! I found it interesting that the researcher first investigated because of his own behaviour, and also the possible links to car crashes and schizophrenia.

As a disinfectant, it is also useful for cleaning any surfaces that may harbor bacteria, including oily skin, preventing acne; it is a key ingredient in skin toners; I used to use it either straight or watered down (it is harsh) or sometimes with witch hazel.
