Nearly 790 million people around the world do not get enough to eat. Most of them live in developing countries. Many parts of the developing world do not have transportation systems in place that can bring food to people. It can be difficult to get food to those who need it without good roads and other necessary infrastructure. But there is a deeper problem. Growing or raising enough food to fight world hunger requires land. If we are talking about raising cattle for their meat that means a lot of farmland and other resources. A group of researchers in California may have found a way to get protein to hungry people. Stephen Mayfield is a geneticist at the University of California, San Diego. He notes that many people are concerned about calories, the energy-producing value in food. Mayfield specializes in algae, the scientific term for simple, plant-like organisms. He says algae have two things that the world needs: protein and lipids, or fatty acids.
