In the past, the Arctic was covered by thick ice all year round. The weather was extremely cold, and it was very difficult for people and ships to enter.
Today, climate warming is causing sea ice to shrink rapidly, turning the Arctic into new shipping routes, a source of resources, and an important military area.
Ships using Arctic routes may travel faster from Asia to Europe and use less fuel.
The Arctic seabed may also contain large amounts of oil, natural gas, and minerals needed to make modern products.
Therefore, countries such as Russia, the United States, and Canada all want to expand their control over nearby waters and the seabed.
Greenland has an important location and rich underground mineral resources, so it has also attracted the attention of many countries.
At the same time, countries are strengthening their military presence, causing the Arctic to gradually change from an area of cooperation into an area of competition.
However, the Arctic is not an uninhabited land.
Local residents, including Inuit people, have lived there for generations.
Less sea ice affects their travel, food, and traditional way of life.
Changes in the Arctic also affect global trade, energy prices, and international relations.
How to find a balance between developing resources, protecting the environment, avoiding conflict, and respecting local residents has become an important global issue.
