Livestock products also benefit the poor by alleviating the protein and micronutrient deficiencies prevalent in developing countries more efficiently than vegetables and cereals. At the low levels of calories consumed by the poor, lack of access to animal products, not overconsumption, should be the concern of policymakers. The effects of the Livestock Revolution on the environment are potentially worrisome, but mainly owing to the pollution caused by large industrial systems of production. Finally, the authors find that the increase in livestock production will require significant additional amounts of feed by 2020, but cereal prices will not rise in real terms as a result. Lack of appropriate policy action will not stop the Livestock Revolution, but it will ensure that the form it takes is less favorable for growth, poverty alleviation, and sustainability in developing countries.
