The United States is one of the wealthiest developed countries, but, according to the United States Department of Agriculture (USDA), 12.3 percent, or 15.6 million, U.S. households were food insecure at some time during 2016. That means about 41.2 million people live in a household where they’re not sure if or when they’ll have a next meal.

This is a problem on a local and global scale. And a growing population combined with a changing climate could mean big trouble for the future. If everyone in developed countries doesn’t have access to regular meals now, what will happen when we’re unable to grow and produce the same amounts of food? It’s a complex issue that often involves politics.

These books offer some perspective from different angles. Learn about poverty in America, food production, and how politics are linked to preventing hunger.
