Answer: The release of methane from thawed permafrost
Explanation:
With increasing global warming, permafrost in the arctic is melting. The carbon and methyl clathrates present in permafrost escape into the atmosphere to form carbon dioxide and methane, both greenhouse gases.
In the Arctic, molecules of methane are trapped in ice crystals as methyl clathrates. When the temperature increases, these crystals release methyl clathrates which become methane when in contact with the atmosphere.
The cause of the increasing atmospheric 
is due to the the thawing of dead organisms present in the permafrost. As the permafrost melts, these organisms decay and release into the atmosphere.
Well, D is definitely correct - t<span>hey both share cultures, especially along the border, because they used to be one country in the past.
I'm not sure about the second answer though, perhaps C (</span><span>They both work together as economic partners.) is correct because they do trade a lot. </span>

<u><em>There</em><em> are three ways in which humans and environment interact with each other</em><em> </em><em> </em><em>:</em></u><em> </em>
- <em>Humans</em><em> Depend on the Environment:</em><em> </em><em>The natural environment is made up of living things and non living things. Humans depend on the natural environment for their basic needs; food, shelter, and clothing.</em>
- <em>Humans Modify the Environment: </em><em>People modify (change) the natural environment to meet their needs. For example, they build dams, plow and irrigate fields, and dig mines. They build houses, schools, and shopping centers on land. This also includes human's impact on the earth's health. Creating pollution, litter and carbon dioxide all affect the earth's condition. </em>
- <em>Humans Adapt to the Environment:</em><em> </em><em> </em><em>Humans</em><em> have settled in virtually every corner of the world by successfully adapting to various natural settings. </em>
- <em> have settled in virtually every corner of the world by successfully adapting to various natural settings. For example, people who live in the northern United States use heating units to keep their homes warm in winter. People in the southern part of the United States use air conditioning most of the year to stay cool in the heat. In addition, in countries where earthquakes are common homes and buildings are built to survive an earthquake. </em>
