How can bison help curb global warming?

It is noted that the European bison disappeared from Romania about 200 years ago, but conservation organisations brought the species back to the Southern Carpathians in 2014, and since then more than a hundred bison have found a new home in the Cărcu Mountains. Today their numbers have grown to 170 animals, and it is one of the largest free-ranging populations in Europe. The population could grow to as many as 450 in the future.

The fresh study uses a model developed by experts from the Yale School of the Environment to calculate the amount of atmospheric CO2 that animals from the wild help capture and store in the soil through their interactions within the ecosystem.
