Good one! I had never heard of gleaning although I do practise it in some of the ways. It does amaze me the food waste from grocery stores and restaurants but one of the worst wastes I had heard of was from the dairy farmers who had quotas to fill which they could not go over or they would be fined plus they could not sell unpasteurized milk to the public so it was thrown out! Yikes!
Let's all keep Gleaning on!
