I have given lectures in the universities of Helsinki, Oulu
and Riga on eco-philosophy, on understanding of the
ecological crisis and on ideological discourses. I have
been active to a varying degree in various environmental
and solidarity organizations. I was one of the organizers
of an international seminar on
indigenous peoples and oil that took place in the
beginning of February in Helsinki. I have also participated
in editing the report of
the seminar (in English) .
