This is really worth rewatching. Many thanks to a supporter in Highgate for emailing it to me. Twelve-year-old Severin Suzuki was addressing a United Nations meeting on environmental issues. Her passion and common sense bring tears to my eyes even though I've now seen this clip many times. It's a powerful reminder of why we all need to keep fighting for comprehensive action on climate change and sustainability. See here for some of my work on this agenda.
