Towards a global model of linguistic ecology

We explore the consequences of the globalization process, which forms new sociolinguistic situations. Specifically, this article explains the tendency of society to be bilingual or polyglot socially, and the linguistic impact caused by the displacement of a majority language group to another area where there is another established code. Of these two consequences and all derived from globalization, public institutions are the responsible ones to deal with linguistic needs and problems. This article also presents the utility of the complex and ecological perspective to solve problems arising from language contact. Finally, we propose the principle of subsidiarity and calls for linguistic sustainability, which international organizations must support within an ethical framework
