This is one of my really passionate issue with the world, ** Food waste **
Isn't it the most dumbest problem? Every time a marriage, celebration, event happens at the end of the day a huge portion of the high quality food is just thrown into a dump. Does just picking up the trash or disposing the waste solve anything or is it just a way corporation schemed us to believe we are doing something for the world by disposing waste.

What exactly do you suggest should have been done with that food then? If people at the end of those events would always give it to the poor then you would have them always loiter around your event. They might even get aggressive, between each other and those from who they get freebies.

Give it to some organization that will handle it? Maybe, but what are the overhead costs for that organization, how long before food goes bad?

There is plenty reasons for just throwing it away and the most important one is: it costs no effort and I think that most people give zero fucks about poor, even if publicly they might say otherwise.

@arraysstartat1 how about a service that at the end of an event can be called which analyses the amount of food and can contact non profit organisations who take care of poor people and deliver it to them. That would be a win-win, no food wasted(hopefully), no poor people will gather around the event, save the money of non profit organisation, in addition reduce carbon emissions.

@Alice that is actually a question I have with myself, do I overeat or dump it? I believe the moment we bought or made excess food, the damage is done. The additional damage is only done to ourself when we overeat.

@Lahsen2016 I don't get how people are so oblivious to this problem. Although i believe no one likes wasting food but somehow our psychological structure has changed to move away from such guilt.

We always keep our leftovers and eat them the next day for lunch. Sometimes we eat the same meal four times...
At parties or other visits, the leftovers get split betweent everyone. So you have no leftovers and everyone is happy, that they don't have to cook the next day.
