39 points.  what is a "drunken forest" and what does it have to do with the topography of eastern europe?

They are found in the tundra regions of Eastern and central Europe. Mostly covered in permafrost, in some areas this frost has melted. The Drunken forest is the reference to the shallowness of where the trees roots are and then the trees start to tip over (Like a drunk man LOL). But within the Northern Hemisphere it alters the life around it and also destroys roads and buildings

Mainly found in the tundra regions of Eastern and Central Europe, permafrost, a layer of perennially frozen subsoil, lies beneath the surface. Recently, permafrost, which is supposed to be continuously frozen, has been thawing in some places. The photo below is a picture of what is referred to as a "drunken forest." Because the trees roots are shallow, when the permafrost melts, the trees start to tip over. The melting of this permafrost throughout the Northern Hemisphere has been altering ecosystems and damaging roads and buildings across Russia and other countries of Eastern Europe.
