Answer: Jahren is a biologist who has a soft spot for leaves, trees and other life giving plant. In Jahren's prologue, she answered people who wanted to know why she didn't study the ocean though she lives in Hawaii. Jahren is concerned about the fate of trees and plants in the world. She believes that a lot of tree are being fell without adequately replacement and that this affects nature.

She believes that the first vital step to becoming a scientist is to care, and not necessarily by ones knowledge of biology, physics, or chemistry.
