Life in the Arctic: People, Wildlife, and Resilient Flora

A Vibrant, Inhabited Polar Region

Unlike Antarctica, the Arctic has been home to human societies for millennia and supports diverse ecosystems adapted to extreme cold.

Indigenous Peoples

Approximately 4 million people live in the Arctic, including over 400,000 Indigenous inhabitants belonging to distinct cultures:

• Inuit (Canada, Greenland, Alaska)
• Yupik & Siberian Yupik (Alaska, Russian Far East)
• Gwich'in (Alaska, Yukon, NWT)
• Sámi (Norway, Sweden, Finland, Russia)
• Nenets, Khanty, Komi, Evenki, Chukchi (Russia)

These cultures are built on deep traditional knowledge: hunting marine mammals, herding reindeer, fishing, and crafting specialized clothing, shelter, and tools.

Iconic Wildlife

Animals possess extreme adaptations—thick fur, blubber, counter-current heat exchange, camouflage:

• Mammals: Polar bear, Arctic fox, Arctic wolf, muskox, caribou/reindeer, walrus, seal species (ringed, bearded, harp), narwhal, beluga, bowhead whale.
• Birds: Snowy owl, ptarmigan, ivory gull, migratory shorebirds/waterfowl (summer).

Hardy Plant Life

No trees. Vegetation hugs the ground to avoid wind and retain heat:

• Vascular plants: Arctic willow, saxifrages, poppies, grasses, sedges, louseworts.
• Non-vascular: Mosses, liverworts, and especially lichens (critical winter forage for caribou).
• Adaptations: Perennial cushions, antifreeze proteins, rapid flowering in 24-hour summer light.

Modern Pressures

Climate change (warming 2-3x global average), industrial resource extraction, pollution (POPs, microplastics), and geopolitical militarization threaten both ecosystems and Indigenous livelihoods.
