Is litter solved by cleanup or social change?

1) What kind of claim is this?

This is a behavioural root-cause claim.

2) What context is assumed or missing?

Evidence about cleanup impact is not described.

3) What has to be true for this to work?

Behaviour change would need to reduce littering more than cleanup alone.

4) When would this not hold?

The claim weakens if regular removal keeps litter at low levels.

5) What follows if we accept it?

Attention shifts toward norms and attitudes rather than labour.
