Dream Catcher leads us to experience how humans are now harming innocent animals without a chance to stay away from danger. The story reminds readers of bioaccumulation in the heartbreaking confession of the protagonist “A-tian" to her animal friends. We should be fully aware that, after all, we share only one earth, and while focusing on just profiting, we humans create a no-win situation. Dream Catcher reflects the author's utmost care for the surrounding environment.
