Food is something which is a must for our survival. Perhaps, everybody work for food only. If the stomache is full then only we start thinking about a resting place, a house. Then comes the family and all other things. Hence without food nothing will work here. The life will be at a standstill.
At the same time, if food is not distributed among everybody, issues start developing in the Society. The access to food become limited to some, while others will lose their freedom to take them. Unequal distribution of food make the Society divided.
In a society where there is this division it is certain that wastage of food will be there. If I look back I recollect certain incidences. When my parents started staying in a new house in a new place (When our ancestral home and properties got partioned we moved to new place), we got a lady servant who was a widow and a mother of two children. The whole family depended on this woman and her income. So everyday she comes in the morning with her son. This was only to share the morning food which were given to his mother. The boy would take a portion of the food to his house for giving to his sister. The lunch also was shared like this. Seeing this my mother started to give more food to the servant such that each could fill their stomach. When I grew up I could see several families around there who had difficulties even to have one meal a day.
Now when I see the food getting wasted, I just remember about those days and those people.
