In part 2, we hear from some of the world’s leading young activists; Jamie Margolin, an American climate justice campaigner and the co-executive director of Zero Hour; Vanessa Nakate, a Ugandan climate justice activist and founder of the Rise Up Movement; and 15 year-old environmentalist, Holly Gillibrand, who was one of the youngest climate activists in the UK when she first began school strikes in the Scottish Highlands where she lives. They talk to Liz Bonnin, Matt McGrath and Victoria Gill about who inspires them and about the pressures of having to step up when they feel some world leaders have checked out.
