The participants of the exchange took part in the debate on the environment. The debate consisted in making each participant choose one of the four options for the questions asked by the facilitator. The participants were of the following positions: I agree very much, I agree, I will not agree, I disagree very much. After choosing one of the answers, a debate began in which the participants shared their views. The questions asked by the teacher were not the easiest ones, for the most part they were very controversial and participants had to think for a long time about the answer and explaining their choice. The lecturer asked, for example: should nuclear energy be developed? can we influence the surrounding environment ourselves? can only rich countries properly care for the environment? The whole debate was very much and the participants were very involved. Exchange of views is very important, especially when it comes to environmental challenges.
