Neo-Malthusians identify the most significant cause of world hunger and poverty as overpopulation. According to Thomas R. Mathus, unrestricted population growth necessarily outstrips economic growth., especially the growth in food supply. Uncontrolled fertility leads to poverty, and poverty leads to the miseries of the poor, including starvation. In 2005, the United Nation’s Human Development Report stated that over a billion people in the world survive on less than one dollar a day while another 1.5 billion people live on between one and two dollars a day. There is a close link between poverty and hunger. Eliminate poverty, eliminate hunger.
