You really should not believe anything he says, In other locked threads, (which were locked due to his open political propaganda) , he claimed he build/retrofitted a dozen of EV. I did not believe it for a second, his stories change all the time. He is on my ignore list for months now.
Now he is after microplastic, lol, not getting anywhere with ev crap so he picks new enemy. The most dangerous pollutant that prevents mankind to thrive are toxic people, fight them anyway you can, ignore them, cancel them, do not associate with them do not hire them, expose them..... etc. If you let them they will pollute your mind, I have a feeling more cancers is caused by them than any microplastic, the stress they cause, invites inflammation, inflammation is main cause of any cancer
