The Siberian Permafrost is one of the largest stores of Carbon as organic matter from many millennia is frozen and stored in the soil. The Permafrost is gradually thawing with warmer temperatures and a lack of animals and grasslands in the region which do not allow the soil to fully freeze over in the winter. The thawing of the Permafrost could lead to a release of large amounts of Carbon as the organic matter thaws and decays. The Pleistocene Park is attempting to reverse the ecosystem shift which occurred 10 thousand years ago and ensure that the permafrost does not thaw. The family has supported this project with a donation in 2020.
