Really? Mine don't - they're polypropylene, and will stick around for a
looong time.

Had a couple full of gravel at the bottom of the garden for a few years.
Both have gone very brittle - the one I attempted to empty and move just
crumbled.

That's not biodegrading. The UV in the sunlight has destroyed them.

O.K. non-bio degradeable :-)
What happens to all the crumbly bits of UV degraded plastic?
Do they work their way into the soil and pollute for evermore?

Main point being - limlited lifespan in planned deployment.
