What? No "Environment" category? Micro- and nano-beads
Just heard a snippet on the radio regarding the environment and one easy, cheap solution.

Lots of make-up products contain micro- and nano-beads to give "body", "feel" or some other quality. Since these are usually made of an insoluble material they can remain in the environment, especially in the sea, for very long periods of time.

This has bad consequencies for most marine life, from unicellular jobs through filter feeders to the top of the food pyramid.

The easy and cheap solution? Exfoliators are abrasive particles in a media. Sugar, from "icing" grade upwards, does not dissolve in olive oil, or some kind if scented skin oil, keeping it slightly abrasive. Salt, maybe ground in a mortar, would also work.So, make an exfoliating paste out of products from the kitchen cupboard and help the environment as well as your wallet or purse!

Going to try it as a gentle smoothing compound on my metal buffer as well. Might be interesting on aluminium, copper or brass. Even silver.

Would it work as a first stage cleanser for painty, oily, greasy etc. hands one might wonder...

Tomorrow is precious, don't ruin it by fouling up today.

How are these beads any more (or less) harmful to the environment than, say, sand?

Huh

Too small to be sifted out at sewage treatment plants, they end up in the ocean, where the plastic becomes a persistent pollutant. As sea temperatures are low, plastic does not biodegrade; it is also ingested by wildlife.

The invisible and the non-existent look very much alike

I suppose sand particles could be ground down to these sub-millimetre, even sub-micrometer, sizes. But those have been part of an environment that evolution has had billions of years to come to an agreement with.

Sand is also much heavier than these plastic beads, does not remain in suspension or get wafted around as much. I would guess any setlled beads remain in the very top layer of any sediment. Until a nearby fish flaps its fins.Think of a filter feeder a mere foot off the sea bed.

The beads tend to obstruct the gut of small animals and form a good breeding ground for bacteria and other nasties.
