Going vegan is a luxury: The adoption of a vegan lifestyle is booming across the world, but it seems to be more concentrated among the rich, according to the Economist. Many restaurants and food manufacturers are keeping up with the transition to the spread of diets devoid of animal products, which are scientifically proven to be better for people’s health and less taxing on the planet’s natural environment. However, the lifestyle is more widely espoused by richer countries, which may have easier access to vegan products and have met enough of their basic needs to think about concerns such as the environment and animal welfare. There is also a growing number of “flexitarians,” or people who alternate between veganism and omnivorous eating habits “In rich countries, people become flexitarians as a response to three concerns: their own health; the health of the environment; and the welfare of animals.”
