Should Everyone be Fed?

From time to time I like to overlap classes and bring in a topic from another class that seems fit to discuss in this class. Today in my future of food class the teacher broke us up into groups to have a debate in whether or not everyone should be fed. When this question was raised, someone turned to me and said I understand it is the moral thing to want to feed everyone, but it isn't the realistic thing. So it is morally correct, but not realistic. Of course she was on the side of playing devils advocate and man people made points that the harsh reality is that to feed everyone isn't going to happen and that to try so will mean eventually depleting what little resources we have left and  making many people suffer for no reason. For no reason? I remember food being a necessity of life and saying that we should save people at the expense of the poor dying is murder and unjust.  Other people that decided to play devils advocate, said that if we interfere with the natural order of things (what's natural about starvation I don't know) then things will never balance out, that things (food and population) will eventually stable each other out.  But an argument from the other side (which I would deem as the moral side) was that we have already interfered with the "natural order of things" and that is why  things are the way they are. We have to just continually interfere with things until we things start to change, because there is no going back now. I believe that everyone should be fed, because everyone is a human and has needs. I know we may not have the resources for it, but if we stop the things that are depleting our resources, like pollution, like war, like deforestation, like building mini-malls and condominiums on farm land and fertile soil, there WOULD be enough. I have a two part question in this blog post, do you think everyone should be fed and what steps can we take to make this a reality?
