Question:

Styrofoam vs. Plastic?

Which is produced by living organisms and which is synthetic: plastic or styrofoam?

Answer:

Polystyrene foam (Styrofoam) is a plastic produced from petroleum sources. It carries the recycle symbol 6. It usually is not recycled and ends up in landfills. Plastic is a general category that includes polystrene foam. Neither various plastics nor polystyrene are produced by living organisms...all are synthetic materials produced by humans (who are living oganisms - did I just contradict myself?).
