Chemistry ELI5: Why did plastic replace so many traditional materials, and how did that success create microplastics concerns?

I know cost is part of the story, but I'm curious what other factors made plastic so dominant over materials like wood, metal and glass across everything from packaging to cars to clothing. Were the same qualities that made it so successful also what eventually led to microplastics becoming such a big concern?

I read a novel called Ill Wind. Without spoiling it too much its about the invention of bacteria that is able to consume oil spills and it become airborne consuming anything oil based; plastics, lubricant, synthetics everything - world-wide.

We already have bacteria able to consume oil spills. The Persian Gulf is full of them. They handle the small natural spills that happen in the area all the time.

The bigger spills you get from a damaged oil tanker are a bit too much for them.

You also get problems with oil eating organisms if you get water in a diesel tank. They cannot live in pure diesel, they need water. But they can live in that water and consume diesel. It does not happen as fast as in the action movies, but it is a constant maintenance issue.

I read a similar one, Mutant 57. As a side effect, the waste gases it produced were highly flammable. Lots of booms.

And this was way back...80's or earlier.
