Vital Connections: Science, Society and Sustaining Health concludes the Sustaining Health dialogue commissioned of Meteos by the Wellcome Trust. The report explores how a growing human population is placing severe pressure on food, water, climate and biodiversity systems. It reviews how advances in health over the past seventy years are threatened by rising obesity, infectious diseases, respiratory diseases and immune dysfunctions – many of which are linked to environmental deterioration. The report explores how recent and extraordinary scientific and technological advances – and ‘Big Data’ in particular – must be used to prevent further decline in human health. It concludes that financial, political, social efforts need to be redirected to achieve this common goal, and identifies five steps to make this happen.
