In my extended family - Quite a large one, the use of a bath brush is usual.

It is just a fairly soft waterproof brush which is wetted, rubbed with soap or detergent lotion and then applied to the skin with varying pressure according to the sensitivity of the area. They last for decades, remove the dead skin and dirt, improve the circulation too.

Many types of marine life is starving to death due to the amount of plastic particles in the water, which they ingest and can't digest, so they clog up their digestion and starve.

The clever idea someone had a few years back where plastic carrier bags disintegrated over time resulted in massive amounts of powdered plastic entering water courses and being carried out to sea. Some coastal water became so cloudy that seaweeds and all the associated life died off for lack of sunlight.
