Global Warming: "Study finds edible fungi could support transition to net zero"

Fungi, is there anything they can't do?*

From PhysOrg:

An Honorary Professor from the University of Stirling has made a breakthrough in resolving a key conflict in the world's quest for net zero—how to reconcile tree planting and food production.
Dr. Paul Thomas's research in Mexico has found that inoculating native trees with an edible mushroom can produce more protein per hectare than pasture-raised beef, while reforesting areas, storing carbon and restoring biodiversity at the same time.

One of the significant outcomes from the global climate conference COP26 was a pledge from world leaders to end deforestation by 2030. Trees are primarily cut down to grow food for the world's growing population. In South America, for example, around 85% of rainforest has been felled to make way for pasture, or the cultivation of animal feed, to produce beef.

Dr. Thomas, affiliated to the Faculty of Natural Sciences at Stirling, said: "Land-use conflict is the major driver of deforestation worldwide, with demand for agricultural output forecast to increase for years to come.

"This study presents a whole new way of looking at land use, making it possible to combine food production—in this case an edible mushroom already appreciated in Mexico—with the carbon sequestration, biodiversity and conservation goals that forestry achieves."

The blue-colored mushroom—Lactarius indigo—was found to produce 7.3kg of protein per hectare, compared with pasture beef production, which produces 4.8-7.0kg. Soya can produce more than 200kg, but is grown as a monoculture, which depletes biodiversity and soil, releasing carbon into the atmosphere....
