Ecological semiotics
ABSTRACT
This presentation draws on my recently published encyclopedia chapter “Ecological semiotics” (Tønnessen 2024). Ecological semiotics, or ecosemiotics, can be understood as the study of sign use by organisms in an ecological context. In ecology, semiotic phenomena and sign processes occur at different levels of biological organization, and distinctive kinds of sign use is characteristic of different kinds of interspecies interaction. Ecosemiotic studies help to explain how ecological complexity can be understood in semiotic terms, and how sentient organisms interpret their environment and make choices that are informed by their sign use. The basic theoretical outlook of ecological semiotics includes lifeworld perspectives, particularly represented by the Umwelt theory of Jakob von Uexküll (2010). This connects ecosemiotics with phenomenology, subjectivity and agency. In a more rudimentary sense, even plants, fungi and microorganisms have agency which can be framed in semiotic terms. A semiotic approach to ecology is particularly pertinent in the context of human ecology and contemporary discussions concerning environmental sustainability. While ecosemiotics is amply informative applied to general ecology, it is especially pertinent in the context of understanding how human agency and sign use affects the environment at large. Ecological semiotics can help us understand how genuinely human sign use stands out from non-human sign use, and the ways in which human sign use is subject to cultural variation. Crucially, a semiotic approach to environmental issues can be informative with regard to understanding how human behaviour and sign use affects non-human lifeworlds by triggering environmental change which is experienced in sign-mediated ways. This positions ecosemiotics to address issues of environmental sustainability.

Wasted GDP in the USA
Abstract
Many believe that the purpose of economic growth is to improve human welfare. Any economic activity has some degree of environmental impact, with higher activity as measured by Gross Domestic Product (GDP) typically involving a more considerable environmental impact. In light of this circumstance, economic growth can be conceived of as wasted if it is not accompanied by improved welfare. In this paper, a concept of “wasted GDP” is introduced. In this perspective, GDP is wasted if it does not support welfare. By estimating what portion of a country´s GDP is wasted, we can assess how effectively the country promotes welfare. The paper is focused on a case study assessing the performance of the United States of America (USA), based on analysis of Human Development Index data. The USA started out as no. 2 in the world by HDI in 1990, but has since been sliding down the list in terms of ranking. While by 2010 the USA was no longer among the world´s 10 most developed countries by this measure, by 2021 it was no longer among the world´s 20 most developed countries. The average US citizen has an income that is considerably higher than the average income in most other countries, including in most rich countries. But despite solid economic growth, over the last three decades the USA has fallen behind several other highly developed countries in the Human Development Index (HDI). 27 countries, large and small, now outperform the USA in terms of nonincome human development, relating to the Health and Education dimensions of HDI. Of these, 22 countries outperforms the USA by nonincome HDI despite having a lower GNI per capita than the USA. I stipulate the share of US GDP that is wasted by comparing US HDI performance with the HDI performance of better performing countries by nonincome HDI that have a lower GDP per capita than the USA. I also estimate ecological pressures related to the USA´s suboptimal human development performance, specifically US CO2 emissions and material footprint related to wasted GDP.
