From climate change, food and water security and sustainable urbanisation, to poverty, health inequality, and migration, responding to the world's challenges as a global society is more important than ever, requiring new thinking that cuts across traditional subject boundaries. This new interdisciplinary degree is designed to address 21st-century issues facing humanity and our planet. It will provide the theoretical knowledge and skillset about our environments and environmentalisms for motivated individuals to develop their careers, as policy-makers, environmental experts and scientists, and advocates for change across diverse fields.A key feature of this innovative degree is the opportunity to take modules across the departments of Biological Sciences, Earth Sciences, Geography and Psychology, with further contributions from other disciplines including options in Politics and Business & Management. Students can choose to specialise through one of several pathways, for example, developing as skilled campaigners able to lead grassroots movements, policy-makers able to develop frameworks for governance, and scientists who are able to communicate state-of-the-art findings in accessible language and with contextual nuance.
