I don't believe anything about you. I am simply telling you what I consider to be the reality.
Some parts of the plastic industry can and will be replaced but far less both short term and long term than people want to think, unless; some new fundamental scientific discoveries are done.
Do you believe I advocate remove all plastic?
Do you advocate keeping all plastic? None of the plastic can be replaced with other materials or designed away altogether?!
I hope you are not, because that is ludicrous.
