Environmental physicist Prof Mark Sutton explains how our fast growing "nitrogen footprint" from agriculture and industry is reaching crisis levels as reactive nitrogen pollutes our air and soil and is a direct threat to human health. A leading researcher and advisor on nitrogen policy, Prof Sutton argues that smarter nitrogen management is not only a health and environmental priority but will prevent continued enormous economic losses. Presented by Dr Andi Horvath.
Virologist Eddie Holmes explains how viral and bacterial pandemics of the type that spawned the Black Death and Ebola remain an unpredictable and inevitable part of our future. Professor Holmes describes how new technologies like genomic sequencing help us explore the origins and evolution of pathogens linked to pandemics as far back as Ancient Rome, and how evolving biosecurity and surveillance systems offer us a chance of containing outbreaks. Presented by Dr Andi Horvath.
Virologist and infectious diseases expert Prof John Fazakerley details the myriad threats to the global food supply from pathogen infestations in crops and livestock, and how new genetic and surveillance technologies are lending hope to keeping them in check. Presented by Dr Andi Horvath.
Transition management thinker Prof Jan Rotmans argues that there must be a radical shakeup of existing institutions and governing structures if we are to deal with the shared, complex challenges emerging in social, economic, energy and environmental realms. Presented by Elisabeth Lopez.
Environmental legal scholar Prof. Robin Craig argues that the doctrine of sustainability in managing our natural resources fails to take into account an emerging age of ecological uncertainty. Instead, notions of sustainability and sustainable development need to make way for approaches based on resilience thinking, which attempts to factor in and adapt to coming large-scale social and ecological shifts brought about by climate change. Presented by Eric van Bemmel.
Atmospheric scientists Prof David Karoly and Dr Robyn Schofield discuss the hole in the ozone layer over the Antarctic, and what effect timely global action taken in 1987 seems to have had in reversing ozone degradation. Presented by Dr Shane Huntington.
Celebrated science writer and author Margaret Wertheim discusses the state of science journalism and communication in a world of fragmented social and digital media, as well as her craft-based efforts to foster scientific and mathematical awareness. With Dr Shane Huntington.
Conservation ecologist Assoc. Prof. Brendan Wintle considers the difficult questions and dilemmas that arise in decisions around species and ecosystem conservation, and whether a monetary value can or should be applied to nature. Presented by Dr Dyani Lewis.
