Is plastic more of a pollutant or glass, before answering this think of the process also and practical things?

Because the process to make glass involves and extreme amount of heat (like 1,000’s of degrees unlike plastic) which emits some kinda smoke which is probably some kind of glass smoke which maybe could get into a person’s lungs like asbestos…
Also, Glass will cut a person and glass shards can stay in the body just like plastic, just thinking of how to compare the two when walking bear foot…plastic seems way nicer.
