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.
Densidade Demográfica no Mundo
De acordo com um estudo realizado pela Organização das Nações Unidas (ONU), a população global atual é de 7,6 bilhões de habitantes. Devido a isso, estima-se que a densidade demográfica no mundo gira em torno de 50,66 habitantes/km² considerando apenas as extensão terrestre do planeta de 150 milhões de km².
Entretanto, assim como acontece no Brasil, esse valor não é representativo e por isso há regiões com densidades superiores e inferiores a média global.
