Even widespread destruction of any one of those would cause massive destruction to humanity as machines, pumps, pipes, water plants, sewage plants, transportation systems, and more fail. Water touching plastic components are everywhere.
I suppose plastics are a bit like antibiotics. The more we use it, the more nature will adapt.
On the other hand, we probably still have decades, if not hundreds of years, before we see the full effect. Plenty of time to prepare alternatives that doesn't carry a usable form of energy inside.
