I agree that some expectations are unrealistic, having strawberries flown thousands of miles for Christmas day is madness. However, this is very different from expecting salad stuff to be on the shelves in June. The shortages as I understand it, are due to a combination of lack of people to pick the salad stuff in the first place, and then a shortage of lorry drivers to deliver it to supermarkets. This has all been discussed quite openly, and we should not be distracted by isssues such as avocados taking valuable drinking water, which is wrong of course. I am fortunate in that I can grow quite a lot of our own at this time of year, but not everyone is able to do so. Concerns about climate change must not be used to cover up problems caused by Brexit
