This podcast is about regenerative movements and as a guest we were honoured to have Karl Thidemann from the US. Karl became aware of environmental issues from a young age and started studying chemistry with the hope of starting to do some environmental work. He understood that the climate crisis was not something that is in the future, and that in fact it is happening right now. He also realized then that the crisis meant that we had to begin very aggressively remove the excess carbon dioxide from the air. Through his work he began to understand that photosynthesis was truly the only practical and feasible option at scale, and therefore founded Soil4Climate to do exactly that. **This material was produced by students in the course Sustainable Organising at Hanken School of Economics in the spring term of 2022. The group work assignment of the course was to design a podcast show and produce an episode about a topic related to sustainable organising.***
