You are forgetting one most important things. Till hundred year back there were hardly 1 billion humans. Now we are 6 billion. And they all the surviving pretty decently. All because of science. The hunger that you are talking was there 100, 1000, lac years back also. If you see all the history, the world is relatively more peaceful and less hungry that it was in old ages. And all because science. Remember you existence is because of science. What you wrote is because of science. If you don't like science please don't use internet. You are at mercy of science remember. In way science is some incarnation of god (if god exists), please respect that.
