Of course this is a fantastic blessing. People in Canada and in the Midwest can have fresh leafy vegetables and a wide range of food from warmer climes.
I met the man who developed the plastic sealing process years ago at a Zen retreat near Carmel, Tassajara Springs.
The technical problem in developing this miraculous technology was to find a gas that prolonged the survival of the vegetables and didn’t escape its container. The gas is nitrogen; abundant, cheap and safe. The plastic, which looks like cellophane took years to develop. The plastic was the great secret discovery.
