Every year tens of billions of animals are raised in terrible conditions in factory farms before being killed for human consumption. Despite the enormous scale of suffering this causes, the issue is largely neglected: every year, only about $290 million is spent tackling the problem globally (for comparison, annual climate change philanthropy is estimated to be $8–12 billion).

Since 2015, Lewis Bollard has led Open Philanthropy’s programme on farmed animal welfare, where he has conducted extensive research into the best ways to end animal suffering in factory farms as soon as possible. 

He might be the single best person in the world to introduce the problem of factory farming.
