Everybody wants to end hunger, but just how to do so is a divisive question that pits environmentalists against anti-poverty campaigners, big business against consumers and rich countries against poor.
The Food Chain Campaign is not about becoming vegetarian, say the Friends of the Earth, it is about putting pressure on the government to mitigate the damaging impact of meat and dairy production on the environment.
"The meat and dairy industry produces more climate-changing emissions than all the planes, cars and lorries on the planet," argues the group. "A hidden chain links animals in British factory farms to rainforest destruction in South America."
London-based Kirtana Chandrasekaran shared the goals of the campaign with Reuters.
