Uexkull's Kompositionslehre and Leopold's "land ethic" in dialogue. On the concept of meaning

Uexkull's famous umwelt theory, which is simultaneously a theory of meaning, remains almost unknown in American environmental thought. The purpose of this article is to create a dialogue between the umwelt theory a source of inspiration for biosemiotics - and one of the major figures of the environmental thought, namely Aldo Leopold. The interest of this dialogue lies in the fact that the environmental thought has much to gain by relying on Uexkull's theory of meaning and, conversely, that Leopold's land ethic is likely to extend Uexkull's thought in terms of ethics.
