We should all chew over such a sad waste of food

Last month, I was involved in an international conference that had the theme of energy- saving and environmental protection. It focused on how to save limited energy and resources in an era when environmental pollution is becoming more and more serious.

However, the theme of the conference seemed to be put aside during the event's dinner.

After the welcoming speech, the dishes started to be served one after another. I took a glance at the menu and noticed it was a rather long list.
