From Bangladesh to Barcelona; Hamburg to El Hierro, issue four of Ethos magazine covers everything from ethical fashion, to electric vehicles, sport and the sustainable development goals. We meet John Thackara, global advisor and public speaker, who advocates for sustainability and the importance of community. Primark gives us the lowdown on its ethical and environmental initiatives. We explore the unique island of El Hierro through our photo story; and we reflect on two years since the plastic bag charge came into effect in the UK - is there really a more ecologically friendly alternative?
