The Forum letter by the Public Hygiene Council offered no new insight except to repeat what has been tried and found ineffective for a very long time (Littering the most critical public health challenge, Sept 11).
To achieve a breakthrough in our efforts to tackle some people's careless behaviour that impacts public health, we must question our long-held beliefs, assumptions and approaches.
A good place to start is in re-examining the stance that "the Public Hygiene Council has long been advocating a carrot and stick approach".
Perhaps the council could consider doing a rigorous review of the literature and consulting professional bodies that specialise in behavioural change to adopt more effective methods of intervention beyond the carrot and stick approach.
