A fun voting system uses plastic milk-bottle tops in different colours to show the categories of voters (such as whether local or not, how often they come to town).

Invite people to vote for two choices out of eight possible ways to make the air cleaner in Winchester town centre - or to vote for "Keep things as they are - pollution isn't a worry for me".

See what people said in our pollution poll in October 2016.

Please volunteer to help for two hours at the farmers' market on Sunday 8 January 2017 between 8 am and 2 pm by emailing chris@winacc.org.uk.
