Since Funko Pops are made out of PVC, which is highly poisonous to the environment type of plastic, one could assume that it automatically makes them harmful to mother nature. However, since Pops are primarily bought by collectors, they don't end up in the trash after a year or so as many regular plastic toys do. When no longer desired, they either get resold or stashed away in a collection that will only grow in value over time, hence not contributing to plastic waste pollution. However, I still hope that in the future, Funko will commit to finding good alternative materials to use instead of plastic.
