World hunger and malnutrition were on the decline for much of the late 20th century. But after falling to 825 million in the mid-1990s the number of hungry people began to rise, reaching 915 million in 2008. In 2009 it jumped to over 1 billion. With a business-as-usual approach to agriculture, population, and energy, 1.2 billion or more people will be hungry by 2015.
