Since plastic doesn’t biodegrade, why aren’t more houses built with plastic instead of wood parts?

Answer 1

Plastic and wood will lose strength and splinter apart over time in almost exactly the same way.

But wood will break down/rot into a dirt like substance which is full of nutrients that can feed new life.

Plastic just breaks down into smaller and smaller particles that replace food for animals/insect’s, but is empty of all nutrients and unable to be processed by animals that eat it.

Over time it will build up in the animal’s digestive system.
Eventually contributing to or causing death.
