I have seen many people who just try to fill their plate to the maximum even if they can’t eat that much. As a result, lots of food gets wasted without any consumption.
We should never leave food in our plate. We should take food a little less than we feel like eating. Most of the time we finish with the little amount of food that we have taken at the beginning and we don't require more. Even if we need more, we may take it again. So what is the point to completely fill our plate the first time?
Those people who just waste food by leaving in the plate must think of those people who don't have enough food for even once a day. If they've a lot of money to waste in this way, then they should try to help and eliminate hunger from our beautiful planet.
