TBH although I'm not a believer in climate change or in any of the climate change scare tactics being used at the moment to scare people into believing it, but at the same time I equally don't think it would be a very good idea to pollute the air that we breath and the food and water that we eat and drink more than is what necessary with pollutants (particulates) such Leaded fuel for cars and lorries and micro plastics in common household products .
Come-on be sensible, its bad enough with all these Climate Change freaks being a sandwich short of a picnic with all their scare stories about the end of the world, but that doesn't mean you have to be one short as well.
So please bear in mind that there is problem a not too serious a problem at the moment but none the less, a growing problem with fuel particulates but micro plastics especially that will given enough time have a detrimental effect on us all as there will be no escape for anybody, anywhere.
The next time your driving, walking, cycling and see a polythene bag caught on something that is fluttering in the air all shredded and faded THINK, what will it be like in a year time when it has shredded and disintegrated into partials so small that you can eat them in your food and breath them in in the air that you breath.
Edit: I see the the question moving creep is at it again, CREEP.
