One way to conserve produce is to buy foodstuff as you see your average food needs. Excess can be given to needy, which can be your next door neighbor or a local slum or maids.

It does hurt to see certain people wasting food, but from where I live, wastage is minimal and either they feed to to animals or to the needy slum kids.

Statistics may so otherwise, but as long as we are doing as much we can, it is fine.
