The UN heads of state and government meet annually for the World Climate Conference and demonstrate, as clearly as in a prayer wheel-like manner, that a global phenomenon can only be countered globally. And yet it took global student protests to reintroduce ecology as a political issue. And just as immediately they called on climate deniers and all those who relativize the urgency of climate change in day-to-day political business. But even the climate-conscious spectrum is by no means ideologically closed. Environmental protection and climate justice, green growth and socio-ecological transformation - the diversity of topics and catchphrases makes it impossible to suspect a closed trend in the history of ideas behind them. However, precisely for this reason it is worth asking about the origins and lines of conflict, motives and contradictions, continuities and breaks in the ideology of ecologism.
