Over the next three decades, we need to make radical changes to the way we produce and consume food. We live in an era where demand is constantly rising – Earth’s population is expected to exceed 9 billion by 2050 – but our natural resources are dwindling. High-meat diets are a particular problem: not only do they contribute to endemic health issues, but maintaining the amount of livestock required to satisfy demand is highly resource-intensive, contributing about 14% of global GHG emissions.
