C. controlled population growth
Controlled population growth has had virtually no effect on farming and is an ideology for the population which is scarcely used in the United States. However, expansive infrastructure and mechanized equipment has kick started mass production of produce, while access to expensive chemical fertilizers and pesticides has helped the United States to grow more quicker and for produce to last longer. The prohibition of hybridized crops has led to a healthier way of farming, such as organic farming which has proved successful and popular in the United States.
