I have been following Precious Plastic and Dave for a few years now and I think this is a true honest attempt. What are your thoughts on micro plastic pollution and it's harmful effects? I have seen a few videos showing people sawing and planing plastic which generates lots of fine particles. Is this going to cause more micro plastics pollution? Is handling these stuff in a home / diy environment harmful to humans?

That's a good question. Sadly there's definitely microplastics involved. Research into microplastic effects is still in very early stages. When you're creating any sort of dust (wood, metal, plastic, etch) particles around humans it's a good idea to have a dust mask at minimum.

My understanding is that most of the microplastic concerns at the moment are about how they're reaching our water sources and oceans. The amount being produced just by washing clothes is relatively scary.
