What Is Precision Fermentation, And Could It Replace Animal Farming?

A new campaign led by RePlanet is advocating for the replacement of livestock farming with precision fermentation (PF) technology. Precision fermentation involves genetically engineering microflora to produce proteins or fats, eliminating the need for animals in the process. This technology offers benefits such as using significantly less land compared to animal farming, potentially leading to rewilding vast amounts of farmland and reversing climate change.

While precision fermentation might sound like a futuristic concept, it is already in use for producing various products such as insulin, rennet, and heme. Advocates argue that this technology has the potential to end animal agriculture, reduce greenhouse gas emissions, and address biodiversity loss. They emphasize the need for governments to embrace and develop PF technology to realize its environmental and food security benefits.
