Thirty years ago a new linguistic paradigm was created when Einar Haugen combined language with ecology. For Haugen, 'the ecology of language' meant the study of the interrelations between languages in the human mind and in the multilingual community. Since then a special branch of linguistics, named Ecolinguistics, has developed in which the connection between language and ecology has been established in a variety of ways and using a multitude of methods and approaches. In addition to the original ecolinguistic topics of language interrelation, language endangerment and language pressure, Ecolinguistics Reader also gives due consideration to the themes of biological and linguistic diversity as well as the ecocritical aspect.
