I took the photo above while travelling in South Africa last year. Whenever I’m faced with the inevitable “But we can just grow corn and soy to feed humans!” anti-livestock rhetoric (as seen in The Guardian this past week), I’m reminded of this picture. It shows tiny rural homes on the edge of a major road, upon which the majority of people walk to work, dodging the traffic as they go. The land is rocky, steep and lacks nutrients, the soil only capable of producing fibrous grasses that can’t be eaten by people. Yet, another few hundred yards down the road, we came across a goat.

For many people in low-income countries, a goat is a lifeline. A source of food that improves the nutrition and health of young children, pregnant women and elderly people. A source of income to allow children to attend school and have a future career, rather than working to support their family before the age of 10. A source of security that allows for improved mental health, female independence and cultural status. Last week I spoke at a Cheltenham Science Festival panel entitled “Should we all become vegan?” It’s easy to suggest that many of us in the developed world could eat less meat. However, the myriad benefits provided by livestock to people in low-income regions should not be foregone on the grounds of foodie ideology bestowed by those of us living in developed regions.

I’m pleased to see Prue Leith, Jenny Eclair, Bob Geldof, Jonathan Dimbleby and others lending their support to Send a Cow’s #UnheardVoices campaign. Let’s recognise livestock’s role in giving hope to those who need it most – and make those voices heard.
