You are really a resourseful man my friend. Many of us didnt realise what effort it takes to bring the food in our table. Like the rice for example, it takes 105-150 days to make it. Consider all the effort of people and how God showered it with love and pour rays of the sun. And here we are can easily throw with no guilt in our heart. If we imagine all of this I dont think anyone will throw away again their food in the garbage.
