Why is the northwest passage important today?

The benefits of a clear Northwest Passage are significant. Ship routes from Europe to eastern Asia are 4,000 kilometers (2,500 miles) shorter. Alaskan oil could move quickly by ship to ports in the eastern United States. The vast mineral resources of the Canadian North will be much easier and economical to develop and ship to market.
Commercial use of the Northwest Passage might be a small benefit of climate change. Billions of dollars in transportation costs could be saved each year if the passage remains open and reliable for a few months of the year. There will also be time and energy savings. Canada has the most to gain should the Northwest Passage become a viable shipping route. This will facilitate Canada's development of northern lands and provide an important economic and military possession if their claim to control is upheld.
