I will not criticise my own Government, but I learned home economics in school, which taught me what cauliflowers and so on look like when picked from the ground. There is a joke around in Cornwall about children thinking that bottles of milk are literally collected from nests, rather than that milk comes from cows. However, the point has been properly made that we need to get to a place where people understand—or have the opportunity to learn, if they choose to—how food is produced, and how they can use it in a much more natural way. I will not say much more on that.
I come back to the intervention about shrink-wrapped cucumber. I accept the points that have been made, and that we can use alternatives to keep cucumbers fresh, but we cannot use the same argument for tinned vegetables. Baked beans, which are already wrapped in tins, are wrapped again in plastic. I cannot see the need for that. Some producers find that cardboard is a useful alternative. I think that the supermarkets and food packagers need to be leaned on by the Government to get rid of unnecessary single-use plastic. I do not think that there is any excuse for using it. I do not want to pick on Mr Kipling, who was a favourite of mine when I was younger, but he likes to wrap his cakes and biscuits in far too many wrappers. It would be great for people to take action about the lack of movement, not only from the Government but from some of the companies that continue to use unnecessary plastic.
The hon. Member for Dunfermline and West Fife—I am sorry; I am really not familiar with his constituency—made a good point about the enthusiasm of local people. There is enormous enthusiasm and determination among the people I meet to cut plastic where possible, so I have three, or possibly four, simple asks.
First, what I hear from people is that when they buy biodegradable or compostable products, they want to know what that actually means. If we buy biodegradable nappies, as I did, how long does a nappy sit in our compost heap before it disappears? I put the nappies in my compost heap—and then I had to put them in the bin about four years later. We need to be really clear with people and have a proper legal definition of what biodegradable actually means. How long should we expect something to take to rot down? What is compostable?
