GMO corn will be the only way to feed all the poor people there
This is a misconception. GM crops are not needed to feed the world and they're not the solution to any current or potential world hunger (although I think they can help).
We already produce A LOT. A huge percentage is however wasted as it don't meets the AESTHETIC criteria the market imposes.
For instance, in the banana business, up to 15% is dismissed because the fruit doesn't look good, even if this has no impact in the nutritional value or the shelf life time. It's the same for any other crop out there, with different numbers of course.
Countries with people starving are the result of shitty policies and systems, not agriculture.
Now, whether GM crops are safe or not, I don't know. But we don't need it, that I know.
