The healthcare sector is a major contributor of greenhouse gases and plastic waste. GASP (the Greener Anaesthesia and Sustainability Project) is a collaboration between anaesthetists and a range of NHS workers, who want to reduce the environmental impact of surgery and anaesthesia. Working on environmental impact in the health care sector is complex, because of the wide range of different disciplines in the healthcare ecosystem as well as the many financial, political and ethical issues . Dr Groome describes how GASP came into existence as well as some of the many challenges and sucesses of this inspirational group of professionals.

Andy Byfield has a long-standing interest in botany, including the flowering plants traditionally associated with arable farming, some of which have become very scarce due to changes in agricultural practices. He has been involved in botanical research and conservation for many years and helped found the charity Plant Life. Recent years have seen increasing interest in our native flora and measures such as the restoration of  wild flower meadows and changes in the management of roadside verges to allow species to flower and shed seed.

Regenerative Agriculture aims to put soil health and sustainability at the heart of farming practices. John Cherry has spent his career farming in Hertfordshire. He became aware of the importance of looking after soil when he noticed farm production was plateauing despite increasing inputs. After a trip to the USA , John was inspired to learn more about regenerative agriculture and he and his family now run the increasingly popular Groundswell conference for farmers and growers who have come to similar conclusions regarding the need to move to more sustainable farming practices.
