Food Waste

I’d a very quiet dog walk this morning - I think most folk were still in bed making best use of the last days of the holiday. I don’t believe in NY resolutions but over the last week have been trying to say hello to everyone I meet on my perambulations - the majority reply and several are up for a blether.
On the way home I was tasked with getting some milk and bread and also nabbed some cut price veg in the reduced price shelves. This area was bursting with soon to be out of date veg all in plastic packets - how much if this will be thrown away ? And at what environmental cost ?
