There are between 600,000 and 1 million vegans in the UK, mostly young females. Vegans do not consume any animal products including meat, fish, eggs, dairy, honey, fur, leather, silk or wool. The UK has a long history of being a world leader in animal welfare legislation, having passed the first law protecting cattle in 1822 and establishing the Royal Society for the Prevention of Cruelty to Animals in 1824. Many people adopt a vegan diet and lifestyle in the UK to avoid contributing to animal suffering from standard agricultural practices and for environmental reasons, and there are over 200 vegan companies operating in the country.
