On the Rationality and Coherence of the Various Paradigms in Ecolinguistics—Based on the “Many” and “One” of Many-worlds Theory

With the development of people's ecological consciousness, the study of Ecolinguistics has become more and more popular among scholars, but the coexistence of various research paradigms and their weak relevance make the unity of the subject unclear. Many-worlds interpretation theory tries to unify in superposition state, demonstrates the unity of micro and macro, and has the potential to disclose the unity of Ecolinguistics. This paper attempts to analyze the level of decoherence and the dimension of multi-worlds from the perspective of Many-worlds interpretation theory, explain the cause of the coexistence of various paradigms in ecolinguistics, and analyze the mechanism of the split of research paradigms, so as to degrade the explicit decoherence and reveal the implicit coherence, which is expected to contribute to the unity of Ecolinguistics.
