When Ángel García was little, he often awoke to the smell of breakfast burritos on the stove. His mom would wake up at 4 a.m. to cook for him and pack his lunch before dropping him off with the babysitter by 6 a.m. so she could get to work. She spent her days picking fruits and vegetables on the farmland surrounding their California home. When she returned at the end of a long day, García remembers rushing to her for a hug, but she would shoo him away. She would remind him that chemicals misted down into the fields where she worked — what kind she didn't know, but she recognized the dangers they posed to her son's health.
