Neo-Malthusians (followers of Thomas Malthus) believe that the solution to poverty is:

birth control

Explanation:

Neo-Malthusians are individuals who follow the claims defended by the Neomalthusian Theory, created by Thomas Malthus. This theory states that the steady growth of the population everywhere in the world is the main reason for the advance of poverty in the world and especially in underdeveloped countries. This theory also states that it is a matter of necessity, that these countries adopt birth control, to reduce the high levels of misery. This theory calls birth control "moral control" and believes that it must be done through contraceptive methods, sexual abstinence and postponing marriages.

Answer: Theory of Population given by Reverend Robert Thomas Malthus stated that population will grow exponentially and food supply will grow arithmetically. Therefore it is believed that his ideologies were thoroughly inclined towards extinction by human greed and exploitation. Most of his follower (Neo-Malthusians) believe that there are exponentially high number of individuals living in this world and the only answer to poverty is fundamental birth control, also counting abortions and vasectomies.
