Net zero: the role of consumer behaviour
Achieving net zero is expected to require changes in consumer behaviour and habits. What are the challenges and how can they be overcome?

Zoonoses are diseases that can be transmitted between animals and humans. This POSTnote summarises approaches to preventing zoonoses with pandemic potential by targeting animal-environment-human interactions. It reviews current biosecurity measures in the UK and globally, notes lessons from COVID-19 and identifies future strategies.

Zoonoses are diseases caused by pathogens (bacteria, viruses, parasites, or fungi) that can spread between humans and animals. In the last three decades, 75% of new diseases in humans have originated in animals. These include all recent pandemics such as the H1N1 (‘swine’) Influenza, and COVID-19 (caused by SARS-CoV-2). Zoonoses are said to be ‘emerging’ when they have recently spilled over into humans or have expanded into to new geographic regions. Emerging diseases represent a global health risk because there is no natural immunity for these diseases among people.
Experts highlight the need for a ‘One Health’ approach to prevent the emergence of zoonotic diseases. One Health is defined by the UK Government as referring to two related ideas: 1) the concept that the health of humans, animals, plants, and the environment we live in are inextricably linked and interdependent and 2) the collaborative and sustained effort of multiple disciplines working locally, nationally, regionally, and globally to attain optimal health for all living things.
During the G7 and the G20 summits, world leaders agreed to implement One Health approaches in future pandemic prevention and preparedness policies.
