Eating insects instead of beef could cut harmful emissions, new study says

New research has shown that eating insects instead of beef could help to tackle climate change by reducing harmful emissions.
The researchers said that replacing half of the meat eaten worldwide with crickets and mealworms would cut farmland use by a third, which will in turn substantially reduce emissions of greenhouse gases.
The paper, ‘Could consumption of insects, cultured meat or imitation meat reduce global agricultural land use?’ studied several substitutes for animal products as sources of both protein and energy.
Using data collected primarily by the UN’s Food and Agriculture Organization, scientists have compared the environmental impacts of conventional meat production with those of alternative sources of food. It is the first study to do so.
1680m hectares of land
Scientists considered a scenario in which half of the current mix of animal products are replaced by insects, lab-grown meat or imitation meat.


They found that insects and imitation meat – such as soybean-based foods like tofu – are the most sustainable as they require the least land and energy to produce. Beef is the least sustainable, the team says.
The group of scientists, which included Professor Dominic Moran of the N8 Research Partnership’s AgriFood programme, says halving global consumption of animal products by eating more insects or imitation meat would free up 1680 million hectares of land – 70 times the size of the UK.
Professor Dominic Moran, N8 AgriFood’s chair in Resilient Food Supply Chains at the University of York, said: “The N8 AgriFood programme focuses on how we can adapt food supply systems to deliver increased resilience and nutrition while reducing environmental impacts. This paper found that we could potentially alleviate some of this pressure by introducing meat alternatives into our everyday diets.”
