Firstly, let me say, I am not pro-either. I just hear about people trying to save the environment (and putting an end to bad municipal 'dump site' behaviour) by rather burning their trash. This is especially true for plastics.
While I try to avoid plastic in general, what are the environmental impact when considering both? To me, it sounds like a lose-lose both ways.
This knowledge could help me swing people who engage in this, in my area.
