Vet Sustain is the organisation dedicated to supporting veterinary professionals to drive change towards a more sustainable future. The world is facing a multitude of complex and pressing challenges including climate change, biodiversity depletion and public health pandemics that present existential threats to human civilisation and the natural world. Veterinary professionals and members of the vet-led team occupy an extraordinary niche at the animal-human-environment interface, and deliver a wide range of sustainability services to society . These services include upholding animal welfare, reducing waste in food chains associated with livestock disease, supporting wildlife health and conservation, and reducing the risk of antimicrobial resistance to public health through responsible medicine use. But as veterinary professionals and members of the vet-led team, we also hold an opportunity to use our skills as multi-disciplinary scientists and our position of trust in communities to leverage change towards a more sustainable future - for our own profession, for the sectors we influence, and for wider society. Vet Sustain believes the veterinary profession can assume a leadership role in addressing some of the most pressing sustainability issues of our time.
