In this episode of podcast I have talked about Arctic and it is itself a very big topic so I have decided to split the video into parts and this is Part1.
About Arctic:
The Arctic is the northernmost region on Earth. The Arctic is dominated by the Arctic Ocean basin, and the icy reaches of Scandinavia, Russia, the U.S. state of Alaska, Canada, and Greenland.
Here are the things I have mentioned.
- Life in the Arctic
Marine Ecosystem
Secondary Consumers
Tertiary Consumers
Scavengers
Terrestrial Ecosystems
- People in the Arctic
- Inuit
- Challenges of Indigenous Cultures
- Resources in the Arctic
- Changing Climate in the Arctic
Additional Information
Balmy Arctic:
The Arctic is mostly an ocean surrounded by land. The Antarctic is mostly land surrounded by water. Because the Arctic ocean absorbs so much more solar radiation than the Antarctic ice sheet, the Arctic is much, much, much warmer than the Antarctic. In fact, the Arctic is not even the coldest place in the Northern Hemisphere. (The icy, subarctic interior of Siberia, in eastern Russia, holds that record.)
Icebreakers:
Travel in the Arctic is still dependent on icebreakers. An icebreaker is a very powerful ship capable of breaking up kilometers of sea ice, sometimes several meters thick. Icebreakers are most often powered by nuclear fuel, but can also run on gas and steam. They can be uncomfortable to travel in, as their shape allows them to roll back and forth more easily than other heavy ships. Russia manufactures the most powerful icebreakers.
Oil in ANWR:
The Arctic National Wildlife Refuge (ANWR), situated on Alaska’s northeastern coast, is the largest protected wilderness in the United States. Extractive activities are allowed in the refuge, as long as the U.S. Congress approves. Some geologists estimate that there may be between 5 billion and 16 billion barrels of oil and natural gas beneath the coastal plain of the refuge. People have debated since the 1970s about whether to develop this pristine area, but Congress has not given any approval to drill or mine there.
