Give the less-developed countries the food not eaten instead of throwing it away

Nowadays, we product 4 billions tons (8800000000 lbs) of food per year. It should feed the double of the world population. In developed countries, it is estimated that 2 billions tons (4400000000 lbs) of food is thrown away in a year and yet in 2013 there are still people who die of starvation because food is too expensive for them.
We must stop with this unfair and inhumane situation. We have the keys to make starvation disappear, so we must help human beings who, like us, have the right to eat their fill, in their human dignity.
