Sir - John Goddard, leader of Oxford City Council, exhorts us (Letters, February 8) not to use plastic bags.

Perhaps he should look at his own city council website, which tells us to "place food waste in securely tied off plastic bags" as well as offering the ambiguous advice: "If you dispose of pet faeces in your refuse, clear up regularly after your pet and place in a securely tied plastic bag before disposing of it in the main rubbish bag".
