Should We All Be Vegans?
What would happen if we all became vegans? Veganism \u2013 cutting out animal products from your diet, and often your wardrobe \u2013 suddenly seems more mainstream than ever. It is attracting followers from Beyonc\xe9 to Al Gore, and there\u2019s a new breed of vegan, too: vloggers espousing their veggie-heavy lifestyle to millions of online fans. Whether it is for health, environmental or ethical reasons, more and more people are embracing plant-based food.
The BBC\u2019s Mike Johnson sets out to explore what the world would look like if everyone gave up animal products tomorrow, and the economic consequences of a meat and dairy-free world. We talk to the owner of the first vegan caf\xe9 in Qatar, we test a meatless burger that \u2018bleeds\u2019 beetroot juice and we weigh up the human cost of an animal-free diet.
