don't waste your food...or else

Have been watching a Taiwanese Variety Program, 命运鉴定团. In one episode, the guest was relating how she "visit" the netherworld and what she saw during her trip down there.

She mentioned, for those whom wasted their food, will get to finish by force eating those food or "mountain of food" that have wasted during their living time...

I heard of such tales in my younger time but one start forgetting about such talks after a period of time. Now, the thought & feeling is coming back to me and I tell myself to eat what I need and say NO when offer especially I know I can't finish eating those food or goodies.

Above all, it is not good to our environment if everyone keep wasting food right? Everyone have their responsibilities to protect this planet we live.
