What we can do
The U.S. has attempted on several accounts to distribute food to third world countries. However, this food had interacted with Genetically Modified Foods and organizations such as Greenpeace convinced them that this food would cause birth defects among their children and other things of that nature.
If organic farmers donated a small portion of their food to be sent t those third world countries, the countries may or may not accept them. In all honesty, the human population is growing faster than food supplies, but this doesn't necessarily mean that this cause is hopeless.
