"Woah! Does that mean those uncorrupted animals, plants, and insects can coexist with humans?" Keith added excitedly.
"In fact, yes," Kisha explained. "Just like before the apocalypse, animals, insects, and plants can still coexist with humans and even fight side by side against zombies and corrupted mutants. Humans have always coexisted with these creatures, and it's this balance that maintains the ecosystem. Now, we have a united enemy: zombies and the corrupted. They only know how to destroy and kill."
Given the common goal of survival, even mutant animals would seek shelter with humans and fight alongside them. However, just like before the apocalypse, many humans still believe they are superior and enslave these mutated creatures. This behavior creates distrust and drives a wedge between humans and mutants.
