Esperanza and Estevan share their culture with Taylor which helps her learn more about the world and gives her understanding of cultural differences. Even the not so important Rhizobia of this book, (Virgie and Edna) help out. They take care of Dwayne Ray and Turtle every once in a while. Every single character helps others in some way and needs helps just like the Rhizobia in bean trees.By incorporating the Rhizobia bugs into the story Kinsolver shows readers that we as humans and as a world are vulnerable. From even the smallest of creatures, like the Rhizobia to the biggest or dominant, like the humans we are all connected. The Rhizobia show us that we can not live and thrive on our own, especially when we have so many problems or “unhealthy soil”. At some point in our lives we will need help, and others will need our help.. Even Mattie, who seems to only help others, needs help sometimes. While it may look like she is doing all of the work to save the illegal immigrants she has many people behind the scenes. The Reverend transports people, along with a doctor who helped for a short time. She also has many other people who live in the space above her shop, some of whom I assume help her out. Eventually of course she also needs Taylor's help to bring Esperanza and Estevan to the safe house. She
could never help all of those people alone because we are all dependent on others sometimes. No matter what stage in life someone is, they will always need help. It is with this help that as a species and world we are able to function. Without the help of others we simply could not survive and would perish completely. Kingsolver recognizes this interdependence and that is why she uses the symbol of Rhizobia bugs such as Taylor and Mattie in the Bean trees.
