🌍 Extreme environments - where only a few dare to live 🌍
Population & places - where's everyone?
- Low Population Density: Imagine having only two neighbors in your whole city block! That's what places like Namibia and the western Sahara feel like.
- Central Australia, Iceland, Northern Canada: 3 people/km²
- Namibia: 2 people/km²
- Western Sahara: 1 person/km²
- Why So Empty? Blame it on:
- Too Cold: Like being inside a freezer in Iceland and Canada.
- Too Dry: Like having the Sahara as your backyard in Australia, Namibia, and Western Sahara.
The unfriendly factors
- Isolated Iceland: Think of Iceland as the cool kid sitting alone in the school cafeteria. Remote, costly to talk to, and everything (even wood) must be imported.
- Namibia's Economic Distance: Imagine being far from the shopping mall and paying more for everything. Namibia feels the same way about the economic hub of southern Africa.
- Coast vs. Inland: Picture coastal areas as posh city centers, while inland regions are the undeveloped countryside.
❄️ Coping with periglacial environments - chill vibes only! ❄️
- Nomadic Lives: Meet the Inuit and the Sami! They move like migratory birds, north in summer and south in winter, just following their reindeer buddies.
- Fishing Frenzy: Love sushi? So do the Nenets of Siberia. In Iceland, fish is not just food; it's money, making up 70% of the GDP!
- Building on Ice? No Problem!
- Raised Buildings: It's like having your house on stilts to keep it from sinking into the melting ice.
- Pre-thawing the Ground: Imagine cooking your frozen pizza first to make it stable. Same with permafrost!
Water & transport - slippery when frozen
- Finding Water: Ever tried digging water out of a block of ice? That's what people in permafrost areas do!
- Transport Challenges:
- Cool Roads: Like wearing sunglasses to look cool and keep the sun away, roads are painted white to keep them cool.
- Ice Roads: It's like driving on a frozen lake, and big trucks use these icy highways in Canada and Alaska.
