Kegiatan manusia terhadap iklim tundra

The tundra is one of the biomes that is the most heavily influenced by the global climate changes in which a significant role has the human activity itself. Till recently the tundra was a place where most of the year there was permafrost and a summer of only a month were the poligonal soil was the dominant landform surrounded by marshlands. But now this period of summer is prolonging year in and year out and it affects the whole landscape as well as the flora and fauna, there's increase in the marshland covered territory some of which are not under ice for 3-4 months, and this period is increasing every year. The mosses and lichens are prospering but most of the fauna is in big trouble. The tundra is actually slowly disappearing because there's no land north of it so that it can be systematically naturally moved because there's only water around the Arctic circle, so very soon this biome may disappear from the face of the Earth.
