Nobody needs to starve when the root cause is focused on. You're basically saying "we will starve people off in the future, but save less people today, so it's actually a good thing". Of the two of us, I'm the one advocating that less people starve.

"When the root cause is focused on" is an extremely vague and non-practical phrase. You can always say "since we have people starving, root cause is not fixed, so we should leave them starving and not help them until it is". What is your method for making "less people"? We have population of 7 billion and growing, Green revolution technology can enable us to feed them. If you deny it, then what you propose to do with those people, where they are supposed to go?
