It seems ironic to be hungry in the world with so much room for cultivation on this planet. If you use logic you will conclude that food should not really be lacking in the world, especially nowadays with so much technology.
The only answer seems to be that our connected markets create a complex mechanism of prices and values, and producers are obliged in many cases not to sell food in order to avoid harm.
I also believe in indoor cultivation in small urban spaces, thus creating a decentralized food system. I did my little ant job, an organic garden on the house wall. Check out the link below:
