Which of the following statements best describes why biologists are currently concerned with global warming and the thawing of permafrost in many areas of the tundra biome?

#Part-B Specialized Branches in Biotechnology

The thawing process will likely decrease the abundance and diversity of soil-dwelling organisms in tundra habitats.
The bacterial decomposition of the thawed organic materials on the widespread areas of the tundra will produce large quantities of CO2, which will add to greenhouse gases and exacerbate global warming.
Oil and coal deposits will thaw and rise to the surface (because of their lower density) of the tundra, destroying millions of acres of arctic habitat.
Populations of humans inhabiting the arctic will have to move to more southern latitudes, resulting in in- creased competition for resources in already densely populated areas.
