Question

Quizplus · Accepted Answer

Thawing of permafrost soils is one of the most serious human impacts in tundra. As permafrost thaws, it releases large amounts of carbon into the atmosphere, which contributes to global warming. It also destabilizes the ground, causing erosion and landslides, and can disrupt ecosystems by changing drainage patterns and altering the availability of water. Deforestation, conversion to agriculture, and gold mining can all have negative impacts on tundra ecosystems, but they are not as significant as the thawing of permafrost soils.
