This article poses the hypothesis that the problem of the intrinsic value of nature that stems from the work of G. E. Moore and is widely discussed in environmental philosophy, bas a parallel in a contemporary discussion in semiotics on the existence of semiosis in nature. From a semiotic point of view. value can be defined as an intentional dimension of sign. This is concordant with a biological interpretation of value that relates to biological needs. Thus. a semiotic approach in biology may provide a useful tool for further analysis of the intrinsic value problem in the biological realm. From an ecosemiotic point of view, the problem is also related to the concepts of bioart and ecoart. Ecoart viz environmental art is that which encompasses the human ambience, e.g., landscape or its components. Bioart call be defined as the art whose material ("clay") is a living body, living matter or communication of organisms (which may include, e.g., genetic engineering). It is concluded that the acceptance of biosemiotic view has implications for a large area of ecological philosophy.

This article compares the methodologies of two types of sciences (according to J. Locke) — semiotics, and physics — and attempts thereby to characterise the semiotic and non-semiotic approaches to the description of ecosystems. The principal difference between the physical and semiotic sciences is that there exists just a single physical reality that is studied by physics via repetitiveness, whereas there are many semiotic realities that are studied as unique individuals. Seventeen complementary definitions of the semiosphere are listed, among them, semiosphere defined as the space of qualitative (incommensurable) diversity. It is stated that, paradoxically, diversity, being a creation of communication, can also be destroyed due to excessive communication.

Fundamental turns in biological understanding can be interpreted as replacements of deep models that organise the biological knowledge. Three deep models distinguished here are a holistic ladder model that sees all levels of nature being complete (from Aristotle to the 18th century), a modernist tree model that emphasises progress and evolution (from Enlightenment to the recent times), and a web model that evaluates diversity (since the 20th century). The turn from the tree model to the web model in biology includes (1) a transfer from modern to postmodern approaches, (2) a shift of semiotic threshold to the border of life, and (3) building the semiotic models of living systems, i.e., the rise of biosemiotics

The field of semiotics is described as a general study of knowing. Knowing in a broad sense as a process that assumes (and includes) at least memory (together with heredity), anticipation, communication, meaningful information, and needs, is a distinctive feature of living systems. Sciences are distinguished accordingly into 'phi-sciences' (that use physicalist methodology) and 'sigma-sciences' (that use semiotic methodology). Jesper Hoffmeyer’s book Biosemiotics is viewed as an inquiry into the sigma-scientific approach to living systems.
