This looks to be another own goal for humanity......

Check this article close to the hearts of beer lovers....

I suspect most UK beer will have the same problem, unless the brewery uses a very deep water supply where the water predates the introduction of plastics.

I'm sure that's right. Even spring water in the Lebanon was found to have the stuff in it, quite how, I don't know, but as it appears to be cycling in the atmosphere and dropping out of the air, I suppose any body of open water will collect the fibres.

This is interesting, seems fleece jackets are a big source of free microfibres!

Better burn mine immediately....oh no, can't do that, CO2 and other toxic emissions! :shock:

Almost any water on the planet nowadays, unless it has been filtering through volcanic rock, or is out of deep aquifers, will have microplastics in it nowadays. It's in the oceans, cycles round with evaporating, and falls in the rain. The micro plastics are not just the breakdown of bottles and bags etc, but nowadays come from the microspheres that are mixed into a variety of products; e.g.,
Shampoos, conditioners, liquid soaps, shower gels, washing powders and liquids, fabric softener; industrial cleaners and detergents etc; the microspheres give that " smooth/silky feeling),
Tissues like kleenexes, toilet paper, ( again for " softness ")
" wet wipes", disposable nappies etc.
The plastic spheres also increase " foaminess" and penetration of cleaning materials.
They are even in writing and printing paper.
These are all Micro spheres, which are virtually impossible to eliminate. Unless specialist techniques are used, even distillation or reverse osmosis won't extract it. A nano filter ( e.g. A graphene filter probably can. And they are moving to " nanospheres" which being so small, can actually absorb into individual cells in any living object. Animal or vegetable.

Seems the Yanks are moving to ban the microspheres....possibly rather late?

I did read a theory by a scientist as to why the earth has never been contacted by another inteligent life form, any other planet that could support inteligent life, after having undergone industrial revolution, has destroyed itself.

That's Sagan and Shklovskii's hypothesis to try to explain in the Fermi paradox.
Harrison speculated that since advanced civilisations may become predators, " good" ones are hiding; "bad" ones are watching and waiting.
Guth argues that civilisations are non-synchronous; so some have been and gone, before finding us.
The "Zoo" hypothesis is that advanced civilisations will watch us but not make contact until they are sure we are safe and sane. Or a version a bit like 2001; we are " nudged" occasionally in various directions
Another version of that is the isolation theory; advanced civilisations realise it is too dangerous to make contact.
There are many other types of theory and lots of shades of the ones above

Another idea from Sci-fi is that any civilisation sufficiently advanced to have developed interstellar travel will inevitably have long passed the 'colonisation urge'. They will be able to transmute elements, control their population, terraform unoccupied planets etc

Lets hope so!

All this talk of alien abductions seems to be something entirely different, and probably much more interesting....but that's another thread! :mrgreen:

It's not Sci-fi ideas; ( though it occurs there, of course; this is serious scientific debate about how/why/when we will or won't find other civilisations. An interesting branch of physics now co-existing with philosophy.
