As Europe faces a heatwave, we meet young people leading the fight against global warming. 11-year-old activist Elliot Powell tells us about his hopes and fears for the environment, and we hear from his mother, Emma, who is one of the organisers of the youth climate movement. And our environment correspondent Matt McGrath tells us whether young people are affecting the climate conversation at a policy level. Also in the programme, workers at Wayfair, the online home goods retailer, are staging a walkout at the US company's headquarters in Boston, over its involvement in furnishing detention centres at the US-Mexico border. We talk to one protesting worker, and get more background from Janelle Nanos, business reporter at the Boston Globe. Plus our reporter explains how American hip hop and rap fans are fuelling profits of the brandy, Cognac.
