If the world wants to limit climate change, water scarcity and pollution, then we all need to embrace "flexitarian" diets, say scientists.


This means eating mainly plant-based foods, and is one of three key steps towards a sustainable future for all in 2050, they say.


Food waste will need to be halved and farming practices will also have to improve, according to the study.


Without action, the impacts of the food system could increase by up to 90%.


Fast on the heels of the landmark report of the Intergovernmental Panel on Climate Change (IPCC) comes this new study on how food production and consumption impact major threats to the planet.


The authors say that the food system has a number of significant environmental impacts including being a major driver of climate change, depleting freshwater and pollution through excessive use of nitrogen and phosphorous.


The study says that thanks to the population and income growth expected between 2010 and 2050, these impacts could grow between 50-90%. This could push our world beyond its planetary boundaries.


So when it comes to climate change, the authors looked at what they called a "flexitarian diet".


"We can eat a range of healthy diets but what they all have in common, according to the latest scientific evidence, is that they are all relatively plant based," said lead author Dr Marco Springmann from the University of Oxford.

“我们可以吃一系列健康的食物,但根据最新的科学证据,健康饮食的共同点就是它们相对来说都是基于植物的,”牛津大学的主要作者Marco Springmann博士说。

"You can go from a diet that has small amounts of animal products, some might call it a Mediterranean based diet, we call it a flexitarian diet, over to a pescatarian, vegetarian or vegan diet - we tried to stay with the most conservative one of these which in our view is the flexitarian one, but even this has only one serving of red meat per week."

“你可以从饮食中摄取少量动物食品,有些人可能将其称之为地中海饮食,我们称之为灵活素食主义,这不是节食、素食或纯素饮食 - 我们提倡在我们看来最为保守的饮食,这就是灵活素食主义,但即便如此,每周你也只能吃一份红肉。”

If the world moved to this type of diet, the study found that greenhouse gas emissions from agriculture would be reduced by more than half.


The study has been published in the journal Nature.
