None of the minorities in American history can share the relations and feelings of utmost complexity as African Americans and Jewish Americans did. They united, they dissented, they fought. Due to historical and racial problems, the complex relations can either be enjoying fraternity or opposing each other, which is quite distinctly embodied in many fictions. As the minorities having a lot in common of similar sufferings and mistreatments in history, the Blacks and the Jews, nonetheless, are almost the same in the literary creation in that they both, when entering the mainstream society, bear bewilderment and helplessness, with a hope of surpassing themselves. Some literary critics argue that there is few ecological writing or environmental writings, but in my view, their environmental description is in a covert way. They do have their environmental concepts in writings. It is because of historical reasons or social status that they are excluded from mainstream ecocriticism. This essay will make a comparison between them in their environmental concepts, carry out tentative study of the covert feature in writing and quest for reasons behind this phenomenon, and eventually come to terms with the "third wave" ecocriticism.
