Reality's Scope On Wolrd Hunger

I have a firm belief that there is no realistic way for us to stop world hunger. It's sad and I don't like to be the one to break the bad news to you guys.
I mean the countries that are suffering from hunger the most are the ones that don't even have the water to sustain themselves, which means that they have no way of being able to support livestock or crops. We can't just ask them to move either. They aren't going to move. They have accepted the fact that they are living on borrowed time. If any of us was in that situation we would move but these families don't have the resources to do that and they lack the drive to do so. Their families have been living there for generations and in those cultures it would be disrespectful to leave your ancestors behind.
For me the only thing that's keeping me from being very depressed about the whole topic is the fact that we are making huge strides in being able to use water from the ocean and being able to harness the wind and the sun to produce power. I'm convinced that there will be a time in the future that we can figure out a way to bring third world countries out of starvation, but its going to take time, time that these people don't have and yet time that they are willing to give. These people know that they are going to go hungry and one day die from it. I just hope that I'm alive to witness the day when we can change all of that.
