Simard grew up in Canadian forests as a descendant of loggers before becoming a forestry ecologist. She's now a professor of forest ecology at the University of British Columbia. She explains her research on cooperation and symbiosis in the forest, and shares her personal story in the new memoir Finding the Mother Tree: Discovering the Wisdom of the Forest.

When Nicole Lynn Lewis got pregnant in high school, she thought it might end her dream of going to college and having a career. She felt ashamed, in part because of how people regarded her as a pregnant Black teenager. Lewis, who is now in her 40s, was named a CNN Hero in 2014. Last year, she was named one of the inaugural awardees of the Black Voices for Black Justice Fund in recognition of her work addressing structural and systemic racism in America. Her new memoir is called Pregnant Girl: A Story of Teen Motherhood, College, and Creating a Better Future for Young Families.
