To eat only a vegan（素食的） diet might sound difficult, especially with many popular dishes containing meat or other animal products. Yet in 2017, veganism was described as “the fastest - growing lifestyle movement” in the UK, according to BBC news.

A study by a UK market research organization, suggests that over 542,000 Brits went vegan during the previous decade, an increase of 360%. And the main force behind this increase was those aged 15-34 years old — 42% of recent vegans fall under that age range.

So why exactly has veganism become so popular among young Brits?

One reason could be that many young people want to protect the environment, as less meat consumption is known to be beneficial to the environment. Global meat manufacturing is believed to cause 18% of the world’s greenhouse gas emissions（排放）, even more than that of all the world’s cars, trains and planes combined. Another reason is that many of today’s young people believe that it’s wrong to kill animals to be used as food.

Jess Murray, 22, a student at University College London, said that he chose to become vegan after realizing that eating animals is a choice that people make, rather than something that we need to do to survive. “Becoming vegan was an ethical (道德的) decision,” he told the Guardian.

Social media is also believed to have given rise to the increase in veganism. Platforms such as Facebook allow young vegans to connect with each other much easier, while others such as Instagram have led to the creation of “vegan celebrities (名人)”, who share lips on vegan lifestyles.

Despite the rising of veganism, Laura Wyness, an expert in diet and nutrition, said that meat is very important for people’s health. “A strict vegan diet makes it difficult to get some minerals and vitamins that your body needs,” Wyness told BBC news.

However, the popularity of veganism doesn’t seem to be fading. “It feels more like this is something that is sticking.” said an expert of the Vegan Society, a UK charity that promotes veganism.
