There is an extreme need now that the children must be aware concerning the current state, safeguard and conservation of the environment. The paper focuses on ecocritical values to children. Children's literature is humorous, motivating, useful, and creative. Eco-writing, in the form of children's literature can enhance environmental literacy. I have analyzed Dr.Seuss' typical children's book Horton Hears a who!, which educates queries and interpretation about the concept and environment of information. Just as the wildlife creatures affects almost what is existent, so would the children as well. This paper is an attempt to emphasize how eco-literature be able to provoke the children in the direction of getting engaged with the environment and to grow their knowledge of environmental conscious and conceptions. It examines Ecocriticism as a field through the critical lens of children's literature. © Serials Publications.
