This article is interesting, it suggests that vegetarian meat substitutes do more harm to the environment than eating meat. There has been widespread news about the impact of meat production on the environment but it seems that meat substitutes such and Quorn and tofu are not as green as they may seem. The Cranfield University found that switching from British bred beef and lamb to tofu and Quorn actually increases the the amount of land cultivated therefore raising the risk of forests being destroyed. This is because the production methods for these products are energy intensive and the final products are highly processed. A vegetarian looking to reduce their environmental impact, then, might be better off avoiding them.
