Michael Alexander Kirkwood Halliday was a British linguist who developed the internationally influential systemic functional linguistics (SFL) model of language. His grammatical descriptions go by the name of systemic functional grammar. Halliday described language as a semiotic system, "not in the sense of a system of signs, but a systemic resource for meaning". For Halliday, language was a "meaning potential"; by extension, he defined linguistics as the study of "how people exchange meanings by 'languaging'". Halliday described himself as a generalist, meaning that he tried "to look at language from every possible vantage point", and has described his work as "wander[ing] the highways and byways of language". But he said that "to the extent that I favoured any one angle, it was the social: language as the creature and creator of human society".
Political ecology is the study of the relationships between political, economic and social factors with environmental issues and changes. Political ecology differs from apolitical ecological studies by politicizing environmental issues and phenomena.
Human ecology is an interdisciplinary and transdisciplinary study of the relationship between humans and their natural, social, and built environments. The philosophy and study of human ecology has a diffuse history with advancements in ecology, geography, sociology, psychology, anthropology, zoology, epidemiology, public health, and home economics, among others.
Ecological modernization is a school of thought that argues that both the state and the market can work together to protect the environment. It has gained increasing attention among scholars and policymakers in the last several decades internationally. It is an analytical approach as well as a policy strategy and environmental discourse.
Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment.
Ecological anthropology is a sub-field of anthropology and is defined as the "study of cultural adaptations to environments". The sub-field is also defined as, "the study of relationships between a population of humans and their biophysical environment". The focus of its research concerns "how cultural beliefs and practices helped human populations adapt to their environments, and how people used elements of their culture to maintain their ecosystems". Ecological anthropology developed from the approach of cultural ecology, and it provided a conceptual framework more suitable for scientific inquiry than the cultural ecology approach. Research pursued under this approach aims to study a wide range of human responses to environmental problems.
This is an example of the form of land management called ecological restoration, which is the practice of renewing and restoring degraded, damaged, or destroyed ecosystems and habitats in the environment by active human interruption and action.(Restoration ecology,on the other hand, is the term coined by John Aber and William R. Jordan III to refer to the practice of ecological restoration carried out explictly as a technique or context for basic ecological research Ecological restoration can reverse biodiversity loss, combat climate change and support local and global economies.
Systems ecology is an interdisciplinary field of ecology, a subset of Earth system science, that takes a holistic approach to the study of ecological systems, especially ecosystems. Systems ecology can be seen as an application of general systems theory to ecology. Central to the systems ecology approach is the idea that an ecosystem is a complex system exhibiting emergent properties. Systems ecology focuses on interactions and transactions within and between biological and ecological systems, and is especially concerned with the way the functioning of ecosystems can be influenced by human interventions. It uses and extends concepts from thermodynamics and develops other macroscopic descriptions of complex systems.
The environmental humanities is an interdisciplinary area of research, drawing on the many environmental sub-disciplines that have emerged in the humanities over the past several decades, in particular environmental literature, environmental philosophy, environmental history, science and technology studies, environmental anthropology, and environmental communication. Environmental humanities employs humanistic questions about meaning, culture, values, ethics, and responsibilities to address pressing environmental problems. The environmental humanities aim to help bridge traditional divides between the sciences and the humanities, as well as between Western, Eastern, and Indigenous ways of relating to the natural world and the place of humans within it. The field also resists the traditional divide between "nature" and "culture," showing how many "environmental" issues have always been entangled in human questions of justice, labor, and politics. Environmental humanities is also a way of synthesizing methods from different fields to create new ways of thinking through environmental problems.
Ethnoecology is the scientific study of how different groups of people living in different locations understand the ecosystems around them, and their relationships with surrounding environments.
The idea of public ecology has recently emerged in response to increasing disparities over political, social, and environmental concerns. Of particular interest are the processes that generate, evaluate and apply knowledge in political, social, and environmental arenas. Public ecology offers a way of framing sustainability problems, community dynamics and social issues. Forests, watersheds, parks, flora, fauna, air, and water all constitute environmental quality and are therefore public goods. The processes society engages in to negotiate the meaning of these goods, upon which decisions and actions are based, reside within the public domain.

Biocultural diversity is defined by Luisa Maffi, co-founder and director of Terralingua, as "the diversity of life in all its manifestations: biological, cultural, and linguistic — which are interrelated within a complex socio-ecological adaptive system." "The diversity of life is made up not only of the diversity of plants and animal species, habitats and ecosystems found on the planet, but also of the diversity of human cultures and languages." Research has linked biocultural diversity to the resilience of social-ecological systems. Certain geographic areas have been positively correlated with high levels of biocultural diversity, including those of low latitudes, higher rainfalls, higher temperatures, coastlines, and high altitudes. A negative correlation is found with areas of high latitudes, plains, and drier climates. Positive correlations can also be found between biological diversity and linguistic diversity, illustrated in the overlap between the distribution of plant diverse and language diverse zones. Social factors, such as modes of subsistence, have also been found to affect biocultural diversity.
Traditional ecological knowledge (TEK) describes indigenous and other traditional knowledge of local resources. As a field of study in Northern American anthropology, TEK refers to "a cumulative body of knowledge, belief, and practice, evolving by accumulation of TEK and handed down through generations through traditional songs, stories and beliefs. It is concerned with the relationship of living beings with their traditional groups and with their environment." Indigenous knowledge is not a universal concept among various societies, but is referred to a system of knowledge traditions or practices that are heavily dependent on "place". Such knowledge is used in natural resource management as a substitute for baseline environmental data in cases where there is little recorded scientific data, or may complement Western scientific methods of ecological management.
Terralingua is a 501(c)(3) non-profit organization under U.S. tax law (#38–3291259) and a registered non-profit society in Canada based on Salt Spring Island in Vancouver, British Columbia whose mission is to support the integrated protection, maintenance and restoration of the biocultural diversity of life. Created in 1996, Terralingua's founders Luisa Maffi and Dave Harmon pioneered the concept and field of Biocultural Diversity, building on emergent ideas about the links between biological and cultural diversity.
Linguistics is the scientific study of language.
A social-ecological system consists of 'a bio-geo-physical' unit and its associated social actors and institutions. Social-ecological systems are complex and adaptive and delimited by spatial or functional boundaries surrounding particular ecosystems and their context problems.

Ecosemiotics is a branch of semiotics in its intersection with human ecology, ecological anthropology and ecocriticism. It studies sign processes in culture, which relate to other living beings, communities, and landscapes. Ecosemiotics also deals with sign-mediated aspects of ecosystems.
Linguistic ecology or language ecology is the study of how languages interact with each other and the places they are spoken in, and frequently argues for the preservation of endangered languages as an analogy of the preservation of biological species.
