Not true... Overproduction of food in first world countries (of course the US) actually increases the populations of third world countries thus increasing the number of people that need food thus increasing the number of people starving to death.
It's ok if you don't believe me, don't expect you to unless you feel compelled to actually educate yourself. "Ishmael" is a great read that addresses this issue, I highly recommend it. Great read. Population dynamics is a huge part of what I've studied, you should look into the concept of "carrying capacity" and how it relates to resource availability. Also, I'm unsure of what you mean by "world"??? I'm assuming the people living in this world? A world that provides for them and gets abused in return?
Before monsanto existed I'm pretty sure humans existed and most were able to feed themselves. And feeding Agent Orange to the entire country of vietnam and a good number of our own American soldiers that fought over there doesn't seem like a very beneficial thing to be feeding the world
Open your eyes. Think critically.
