Petra Kelly was a co-founder of the German Green Party and known worldwide as a champion of ecology and human rights. She was tireless, fascinating and inspiring. So it's no surprise that her ideas and initiatives live on in today's politics: in the fight against climate change, for gender justice and the global validity of human rights. This year, the Heinrich Böll Foundation celebrates her 75th birthday and commemorates her violent death 30 years ago.

Evolving around the main essay “Sharing life. The Ecopolitics of Reciprocity”, all contributions to this assemblage reflect a common understanding that ecology and biodiversity needs to be reclaimed – and constantly generated – as a process of lived and living realities in a system of reciprocal relationships.
