A Sexta Extinção em Massa e a Catastrófica Ecologia do Antropoceno: Tecnodiversidade e Metanarrativa de uma “Nova Época”.

Abstract

Among the many characteristics of the Anthropocene is the fast rate of species extinction, phenomenon known as the Sixth Mass Extinction. Besides the loss of biodiversity and consequent damage to the biosphere, other characteristic of the Anthropocene is the increase of the technodiversity and consequent enforcement of the psychotechnosphere. In this thesis it is realised an analysis of the process of biodiversity loss and technodiversity increase in the municipality of Ipê, state of Rio Grande do Sul, through a perspective based in the Archaeology of the present and the contemporary past. Besides that, this thesis aims to comprehend the Anthropocene’s metanarrative, showing the many and intense debates that occur about this proposal of a “new epoch” in the planet’s history. The method applied consisted in two phases that searched to correlate the perceptions of the dwellers of Ipê about the changes occurred in the anthrome in that they live in the period between the years 1968 and 2018. In the first phase, that consisted in an etnoarchaeological research, were collected and analysed data that indicate alterations in diverse environmental indicators that points to a crescent anthropization of the municipal territory. In the second phase, that consisted in the analysis of the technofossils kept in the Ipê Historial Museum, was constated changes in the constitution of the technodiversity that indicate a crescent artificialization of the environment.
