Hello what can you tell me about Nunavut...specifically its Geography?
Actually, I can tell you many things but let's start with this, Nunavut is the largest area wise and the second-largest in the population among Canada's provinces and territories.
tell me something else?
Sure. Nunavut has long land borders with the Northwest Territories on the mainland and a few Arctic islands, and to the south of the Nanavut mainland is Manitoba, and it also meets Saskatchewan to the southwest at the quadripoint.
Is there anything else you can tell me?
Sure. Nunavut also shares maritime borders with Greenland and with the provinces of Quebec, Ontario, and Manitoba.
maritime borders what is that?
Sorry, I don't have information on that but you might be interested in knowing that the highest point in Nunavut is Barbeau Peak on Ellesmere Island, which is 2616 m.
wow that is interesting. Now what can you tell me of the economy?
The people of Nunavut primarily depend on diesel fuel to run generators and heat homes, there are few to no roads or rail links to the region, so the fossil fuel shipment arrives from southern Canada by plane or boat.
is there anything else you can tell me?
Yes, there is. The region of Nunavut is warming about twice as fast as the global average, according to the UN's Intergovernmental Panel on Climate Change.
Thank you so much for all of your help
