Question

Are there organisms that have incorporated (manmade) plastic into their lives in any way? Either in their diet, or as a part of their body?

Answer 1

There may be! There is an insect called a caddisfly. It creates its own home out of many things on the bottom of rivers, and that can include plastic. (See this video for reference: https://www.youtube.com/watch?v=Z3BHrzDHoYo)
