Regardless of all the technological and agricultural improvements made since the end of the 18th century when Malthus wrote his essay on population, there are more people living in extreme poverty today than there were people (in total) living when his essay was published. This is consistent with what Malthus claimed: there is no way for human population centers to live within their means -- any increase in resources will inevitably lead to a rise in population until the available resources are again insufficient to maintain the population.
The seemingly noble cause of ending world hunger, if doable even for a relatively short time, would ultimately lead to more poverty and hunger (barring some unknown hole in Malthus' theory). Is it ethical to help someone in need today if you are quite certain this will only cause more people to suffer later?
