Question

Why are there increasing problems with construction in permafrost regions?

Answer 1

The reasons are as follows;

1) Existence of black spruce tree (2)Global warming (3) Booming arctic populations (4) Longer freeze-thaw cycles

Answer 2

A permafrost region is a thick subsurface layer of soil that remains below freezing point throughout the year, occurring chiefly in the high latitudes and altitudes.

Construction is having increasing problems in those regions due to the instability of the area for global warming. It is damaging the ecosystems and damaging the existing roads and buildings.
