Everyone should be charged a small fee to get a plastic bag with their shopping, according to a group of environmental pressure groups.
Samantha Harding, of the Campaign for the Protection of Rural England, says a fee of 5p would "seriously reduce litter and pollution... which is having a massive, massive effect".
Judith Holder, author of Grumpy Old Women, believes that a five pence fee would not work.
Her life is "full of bags", she told the Today programme, "my problem is I've never got them when I got to the till."
People need to be charged £1 for a bag so that they remember to take them in the shop, she suggests.
