Recently, two papers were published that, in different ways, illustrate the huge challenges we face in delivering global food security. In the first, it was shown how nearly half of the greenhouse gas emissions from producing a loaf of bread arise from the nitrogen fertiliser used to drive wheat cultivation (Goucher et al. 2017). With over 100 million tonnes of such fertiliser used annually to support global food production, and the other impacts that arise such as pollution of water courses, the unsustainability of modern agriculture is exposed. In a second paper, the interconnectedness of the agri-food system was elaborated and a compelling case presented for joined-up thinking when devising future policy. This should be one that analyses together environment, land-use, food production, food consumption and human health. Futhermore, it should be one that fully considers the development and expression of agri-technology in the context of the complex cultural, political, ethical and economic tensions that arise (Horton et al. 2017). These two papers lead to the conclusion that only a radical change in the way we produce and consume food will deliver a sustainable and just global agri-food system. In this article the nature and causes of the problem are identified, and possible solutions defined
