What connections does Red make between the two species of humans and trees?

Many times within the narrative of Wishtree, Red points out the differences between humans and trees. However, Red also finds similarities between these two widely disparate groups in order to show how all living beings are connected to one another. Red states that humans use body language, for example, and trees use a similar “dance of sunlight and sugar, water and wind and soil” (21) to communicate with other beings.
