As a child, I remember feeling hungry most of the time. Growing up in rural Tanzania, I walked to school barefoot and most of the time had one meal a day. After school, I helped my mother with various farming chores, including feeding the animals, weeding, harvesting and planting. I often heard my mother express concerns about the lack of ways to protect our crops from drought, pests and diseases. I wanted to help my mother but was too young to understand what the solution might be.
