Haderach C. Kwisatch"Some species of fig trees store calcium carbonate in their trunks – essentially turning themselves (partially) into stone, new research has found. The team of Kenyan, U.S., Austrian, and Swiss scientists found that the trees could draw carbon dioxide (CO2) from the atmosphere and store it as calcium carbonate ‘rocks’ in the surrounding soil.
"The research is being presented this week at the Goldschmidt conference in Prague.
"The trees – native to Kenya – are one of the first fruit trees shown to have this ability, known as the oxalate carbonate pathway…"

From air to stone: The fig trees fighting climate change
Kenyan fig trees can literally turn parts of themselves to stone, using microbes to convert internal crystals into limestone-like deposits that lock away carbon, sweeten surrounding soils, and still yield fruit—hinting at a delicious new weapon in the climate-change arsenal.
