It might be time to swap animal protein for similarly-delicious fungi.

Replacing beef with microbial protein benefits the environment, annual deforestation may be cut in half if 20 percent of per-capita ruminant meat consumption was substituted with microbial protein by 2050. This substitution would offset future increases in global pasture area, which can also cut related CO2 emissions in half, says Florian Humpenöder, study author and senior scientist at the Potsdam Institute for Climate Impact Research.

“The production of ruminant meat requires large areas for cattle grazing or growing its feed on cropland, which causes deforestation, biodiversity loss, and CO2 emissions,” he adds. “Today,of global agricultural land including cropland and pasture is used for feeding livestock.” Although the production of microbial protein has considerably lower land use and GHG emissions compared to that of ruminant meat, its energy consumption isto that of beef production. The entire process of microbial meat production—which includes electricity generation, microbial cultivation, bioreactor stirring and cooling, and the eventual downstream processing of biomass and proteins—requires energy.

If our food systems were to increase the production of microbial protein or other biotechnology-enabled alternatives , it’s necessary for electricity generation to be
