Thousands of people have flown to Copenhagen this week to join today's protest about climate change. The protesters say that world leaders are not doing enough to combat global warming.
One of the organisers of the protest, Cnut Cnutsson spoke exclusively to me:
"These leaders are just not taking this seriously enough. I mean, they've flown here from all over the world to have a week-long meeting to discuss climate change in the hope that they will have a legally binding agreement about controlling CO2 emissions and other things that cause climate change. I mean, come on!! They can do better than that. That's why we're protesting."
When asked what else the world leaders could do about climate change, Mr Cnutsson said, "Well, they could all fly over here again next month for another meeting."
He continued, "Oh yes, and stop the war too! I know that's got nothing to do with climate change, but we just use any protest as an excuse to mention that."
