Thirty years ago, a new linguistic paradigm was created when Einar Haugen, for the first time, 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 by using a multitude of methods and approaches. This reader contains important articles from all the different fields of ecolinguistics - a volume long overdue for a discipline now recognized as a significant contribution to variety within the subject.
