It's Okay To Be Smart (1 year ago)
Regarding use of the word "Eskimo" in this video: We are now aware, thanks to many polite comments from our audience, that this is viewed as a derogatory term among many native peoples of Canada, as well as in some Arctic regions. Several of our references centered on Alaskan natives, among whom this term is more commonly accepted. Additionally, we used the term in reference to native languages, which are more commonly referred to as Eskimo or Eskimo-Inuit, and not the people, but we should have been more clear and sought out another term. We apologize to those we offended, and have learned a lot. We'll do better in the future, as we always aim to do.

It's Okay To Be Smart The collection of languages among the actual people is actually Inuktitut. Just because some groups are chill with it doesn’t mean it should be used by outsiders, just like with any other slur.

According to Yupic Eskimos of Western Alaska, Igloos are a fake invented by a Hollywood director for an early silent film. They just laugh at stupid "gussuks" who believe they were real.

I’m actually Alaskan Native and I am Inupiaq, or Eskimo. The word Igloo actually means “home” but our actual word for it is something along the lines of Igluoq, but. when the Russians came they just made it igloo. also, we actually didn’t live in igloos. we made them for storage of animals that we killed and as a temporary home for hunting during the winter. Our more permanent home during the winter were semi-subterranean homes, which the permafrost in the ground and bones from dead animals helped structure it. i get all of this information from my ancestors and firsthand experience, and also because I worked at the Alaska Native Heritage Center. Message me if you’d like more info

John B Ok, no problem. But what do we call them next year and a few years after that? I don’t know anymore what is going to offend some one. What do you call a person with really dark skin, or light brown skin???? I am afraid to call them anything. My sister and I are white but we often call each other white honkys. Lol

Virtuitous Vampire (1 month ago)
You don’t call Inuit “Eskimos” anymore. It’s derogatory to Inuit people as it means “raw meat eater”. So please don’t use it. The one thing about Inuit is in their culture they choose their own names when they are older. Calling them a name that they wish not to use for their own people is in fact demeaning.
olly bro (1 month ago)
Virtuitous Vampire and I never said they had a bad culture, I find it impressive they survived the conditions. I have just never been taught it or never thought to learn it.
olly bro (1 month ago)
Virtuitous Vampire okay, first I knew they were not still hunting rabbits or whatever they did hunt, I will use the term Eskimo when I am talking from someone HERE. When I am over THERE, i will use the term Inuit so not to offend anyone. Most middle class people here do use the term Eskimo, NOT in a offensive way, but that’s just what we call you. Again, we don’t mean anything by it, it’s just the thing we call you. I’m ww2, we called Americans yanks, not as a insult, but that’s just the thing we called them. Sometimes for a little joke, sometimes just second nature. Don’t think British people walk around calling people names and being racist for Christ’s sake lol.
Virtuitous Vampire (1 month ago)
olly bro I’m from Canada and live in an area with Inuit and First Nations people. And from where you live it’s quite obvious your ignorance of Canadian and indigenous cultures are something to be imagined. Yes, it is demeaning. The term “Eskimo” has actually been eliminated from our history books for the last 40 years because of Inuit and indigenous human rights and what is called reconciliation from what the British and colonizers did to Inuit culture. So again, maybe you should LEARN about how other people live and cultures because you are actually not even in modern times. I’m trying to inform you. It’s up to you to actually understand what you say may be offensive to other cultures. Just because you say it doesn’t make it so. Go to Nunavut and say the word “Eskimo” and you will find yourself in a frozen lake. And just so you know Inuit people don’t necessarily even live in igloos anymore. They use modern snowmobiles instead of sled dogs and most eat the same food as everyone else because it’s flown and trucked in. Don’t think that Inuit people are behind the times like they were Neanderthals and hunt walrus, polar bears and fish everyday. They are human beings that still have their culture and food, but now have modern conveniences and technology and actual human rights. When you call them a name they don’t want to be called, you are actually taking those rights from them and further trying to colonize them to what you believe they should be. That’s wrong and disrespectful.
olly bro (1 month ago)
In fact wherever you come from, I would imagine America, it may be hurting their ‘ feelings’. But I’m British, over here in Europe it has no offensive meaning. It is just generally what we call them, because well, that’s the best known word for them. So I’m sorry if it’s offensive over there, but here it’s just the word we use.

With the entire system relying on a lack of air flow rates out of the igloo, I wonder what the CO2 percentages are after long-term igloo usage.
almin livak (1 month ago)
It's okay to be smart even when you're not smart enough to know that water expands when it freezes and a cubic meter of ice (920ish kg) doesn't weigh the same as a cubic meter of water (1000 kg) 2:54 not that 80 kilos makes it all that much heavier but if you're going to throw in a number make sure it's the right one
