Grass cutting work exposes hidden littering problem

Whenever I see workers cutting grass to improve the looks of roadsides, the result will often be worse than before.

This is due to the plastic bottles and other rubbish that had previously been hidden by the tall grass.

My question is: why can’t we also make grass cutters responsible for picking up rubbish and disposing of it? That way, the real benefits of grass cutting could be seen and appreciated by everybody!
