It emerged this week that scientists in South Korea have created a new kind of “meaty” rice, with high levels of protein.  The grains are packed with beef muscle and fat cells – all grown in a lab.  It’s just the latest of many meat-alternatives that are helping people to eat less meat.  Supermarkets are responding to public demand by offering an ever wider choice of plant-based foods.  But while we might not need to eat meat, most of us really enjoy it.

The goal posts are shifting in the age old debate about the morality of meat.  Whatever you think about the industrial breeding of animals, to be slaughtered and served up for our pleasure, there’s now another compelling argument for us to stop, or at least cut back – meat production significantly contributes to climate change. 

In the last decade, the number of vegans in the UK has increased steeply, but it’s still small. Estimates vary between about 2% and 3% of the population.  Many more are vegetarian, who avoid meat and fish, but eat dairy.  There are also flexitarians, who mainly choose a plant-based diet, but do occasionally eat meat.  

A moral argument that was once focused on whether humans have the right to exploit animals has become a broader debate that includes protecting the planet for future generations.  Some say it’s natural for humans to eat meat, indeed we have evolved to do so.  Others think it’s barbaric and the effects of the meat and dairy industry on the climate have made the argument for veganism overwhelming.   What’s the moral case for veganism?
