"It seems like everyone is in an odd sense of denial about climate change. I was in a quandary about what I could do. I felt taking part was a way of putting my name down and doing something for the environment. It was an incredibly peaceful demonstration and I think we put down some kind of marker. The message is really very slow to get through to people, but it will come to us all, we will all have to deal with the impact of this climate emergency. I hope this kind of action has caught the public imagination. It is the new future."
