Full Answer

Global warming is considered such a major threat because it is likely to melt the characteristic permafrost of the tundra, altering the biome dramatically. Human influence in the form of air pollution and construction of roads and pipelines is also likely to damage the tundra biome. National Geographic indicates that it is important to create protected areas and reserves within the tundra biome, limiting human influence. National Geographic also encourages limitations on tourism and construction in the tundra.
