During one workshop, a slightly modified oxford debate was organized. Modified because the participants were divided into two groups with no specific division of people into roles. Everything else was left to the debate phase, for example. The main topic was the thesis "Only rich countries are able to take care of the environment". Both groups had to prepare an argument under what they drew: an opposition to the thesis or a proposition. The debate lasted more than three hours. The first phase was to prepare for it, and the second phase was already a debate. Everyone actively participated in the argumentation, but the proposal team was better. Nevertheless, the debate was held at a very high level.
