Introduction

Joseph Port led a study on 40,000 farms in almost every country. He assessed the full food supply chain from deforestation and clearing of land for agriculture right through to processing, packaging, transport and retail. The lowest impact beef is using 36 times more land and creating six times more greenhouse gas emissions than peas and beans. Peas and beans are all relatively low, peas and beans are some of the lowest but you've also got tofu which even the highest impact. Even if you want to get it from Brazil for example. Most of the soy we buy in the shops in the UK to eat doesn't come from the Amazon. It comes from Europe, there's actually soy grown in France and
