@dalias I agree with Greenpeace on this. Like the other person who responded, I used to work for Greenpeace. Plastic is a horror.
I can't remember any campaigns they've done that were wrong-headed. I still let what I learned canvassing for their dioxin campaign guide my family.
I think we need purists. I try to be a purist myself, under the belief that if I'm not part of the solution, I'm part of the problem. Nothing that involves victims is acceptable, and we all live in a real life version of the Twilight Zone episode "Button, Button" nowadays.
I'd love to have a 3D printer, but I won't get one because it's all plastic. So instead we collect woodworking tools. The kids use clay for things. Are there things for which a 3D printer would be wildly convenient? Absolutely. But it would be convenient in the way Amazon is convenient or gig economy companies are convenient. In this case, looking for the victims would be particularly easy - my kids would be among them given microplastics pollution.
The only crap like that we're allowing inside our bodies is mRNA vaccine carrier, and even there people are moving beyond polymers.
I'm going to hash-tag this as I want to boost it. I really care about this and want to offer more people the perspective that guides us.
