Tundras are among the world's coldest, harshest biomes, with extreme temperatures and low rainfall. In the winter it is cold and dark, and in the summer when the snow and the top layer of permafrost melt, it is very soggy and the tundra is covered with marshes, lakes, bogs, and streams. Natural gas is a more recoverable resource than oil in tundra eco-regions. Today, Arctic cultures such as the Inuit and Sami have access to high-quality building materials and sophisticated structural engineering plans. Precipitation in the tundra totals 150 to 250 mm a year, including melted snow. Barren tundra lands are home to hardy flora and fauna and are one of the Earth's coldest, harshest biomes. Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. 76% percent of natural gas and 79% of oil were exported to Europe, with the second largest customer for oil being China and for natural gas being Japan.

Goal 12: Sustainable Consumption and Production. Phosphates are used as fertilizers in agriculture, with other uses including water treatment, flame-retardant materials, and corrosion protection. The tundra is also slow to repair itself from physical disturbances such as tire tracks from heavy vehicles. 21st century tundra shrubification could enhance net carbon uptake of North America Arctic tundra under an RCP8.5 climate trajectory. The Arctic experiences the extremes of solar radiation. The Earth depends on regulating mechanisms and air circulation patterns the tundra provides to keep climates steady worldwide. Tundra Threats.
