Marie, Hannah and Charlotte are conducting audience research. There are different types of vegetarians such as semi-vegetarians, pescatarians, lacto-ovo vegetarians, and vegans. People become vegetarian for reasons like animal welfare, health benefits, religion, and environmental sustainability. A typical vegan meal may include foods like tofu, rice, lentils, chickpeas, and oat milk. The number of vegetarians in the UK and USA is growing, influenced by factors such as education and awareness campaigns.
