Well-fed world can slow warming too

The hopeful news is that by mid-century a well-fed world may be able to feed everyone alive, while halving the gases causing global warming. There’s just one snag: for most of us it would mean an almost meatless diet.

On 8 October global scientists said the world must make “rapid and far-reaching changes in all aspects of society” to keep global warming from reaching unacceptably dangerous levels.  They included the food we eat as one sector demanding radical change.

Bang on cue, a report by a separate group of scientists says the 10 billion people expected to be living by 2050 could enjoy sustainable food supplies – while emissions of the greenhouse gases that are warming the Earth fall by more than 50%.

But, for this to happen, the rich world would have to pay a high price, while the poorest people still faced malnutrition and hunger.

Less animal protein

The report says Westerners need to make a drastic switch away from meat and dairy products, cutting their consumption of beef by 90% and eating five times more beans and pulses than they do today to stave off hunger. Similar though slightly less radical changes are in prospect for people in other prosperous countries.

The researchers who wrote the report, published in the journal Nature, "Options for keeping the food system within environmental limits"  say it is the first to quantify how food production and consumption affect the planetary boundaries that define a safe operating space for humanity, and beyond which the Earth’s vital systems could become unstable.

“No single solution is enough to avoid crossing planetary boundaries. But when the solutions are implemented together, our research indicates that it may be possible to feed the growing population sustainably,” said Marco Springmann of the Oxford Martin Programme on the Future of Food and the Nuffield Department of Population Health at the University of Oxford, UK, who led the study.
