Why should permafrost in its areas of distribution need to be preserved?

Permanent permafrost must be preserved primarily in order not to harm nature. Also, thawing of permafrost jeopardizes human economic activity in these territories.
Under the influence of human economic activity, permafrost sometimes thaws, rocks float and at the same time the foundations of buildings, pipelines, railways and roads are destroyed. Also, in permafrost, the remains of those animals that lived in the preglacial period are well preserved and are of great importance for science.
