Dale Vince, a vegan and climate activist, is advocating for bacon to carry cigarette-style health warnings in the UK due to its links to cancer and environmental destruction. He believes that changing dietary habits is crucial for reducing carbon emissions and improving human health, with meat consumption being a significant factor. Vince is calling for government intervention, including placing warnings on meat and dairy products and changing menus in institutions like the NHS to promote healthier eating habits.

Vince is supporting a campaign by Plants First Healthcare to make UK hospitals plant-based by default, as animal products are currently served to patients despite their negative health impacts. Numerous studies have shown that plant-based diets are associated with lower disease risk, highlighting the benefits of eating more plants and less animals. Vince draws a comparison to how tobacco is regulated, suggesting that bacon, classified as a class one carcinogen by the World Health Organization along with tobacco, should be treated similarly with warning labels and restrictions on availability.
