konstantin gorodetsky: i have counted about 250, maybe 300. it's a lot less than other german cities. konstantin: yes. eric: is it difficult to do a protest like this in this coal town? konstantin: yes, it is. we already had demonstrations against us, which is uncommon in every other german city, i think. eric: yeah, so, do you feel a bit divided, being from a coal community but protesting against coal? konstantin: i am not, because we all know that we have to end coal. the question is how fast we have to do it, and the answer is in my opinion that we have to stop it as fast as possible.
