The merits of eating less or no meat in a bid to improve environmental sustainability have been frequently debated in these pages and elsewhere. This week saw the launch of a new book, Meat, The Future: How Cutting Meat Consumption Can Feed Billions More, which delves deep into this question, covering meat-related issues ranging from water and carbon intensity, to health and food security. One chapter, written by us, focuses on the influence of dietary choices on world phosphorus use from fertilisers, and the fate of these nutrients in the ecosphere. When Al Gore released his influential movie, An Inconvenient Truth, he focused on how changing our energy systems could reduce our greenhouse gas emissions, and therefore mitigate climate change. But he was roundly criticised for ignoring another significant source of greenhouse gases: livestock and eating meat. To his credit, Gore took this critique on board and subsequently adopted a plant-based diet. The difference between the two estimates was mainly down to differing assumptions about the lifetime of methane a potent greenhouse gas in the atmosphere. There can be no doubt that it is a significant and growing contributor. The linkage between food, diet and global sustainability has not had the attention that it deserves. Phosphorus is a unique and critical global resource, essential for growing crops as for nitrogen but impossible to substitute or manufacture. The use of phosphorus is influenced by changing diets in a major way, with the global growth in per capita consumption being driven by the increase in the consumption of animal products.
Dwindling water is the next big global resource crisis looming over us, and soil depletion isn’t far behind. Living in a green home doesn’t instantly equate to a low-impact lifestyle, if for example you have a long gas-powered daily commute and you eat a 12 ounce steak every night.

Asparagus can be said to be the fancy cousin of broccoli, and there is a big difference in their water consumption. Broccoli requires about litres of water per kg – similar to the requirements of cauliflower and brussels sprouts – whereas asparagus requires almost 2, litres per kg, or about 8 times as much. Millet has been referred to as ‘the new quinoa’.
