The biggest environmental issue in Norway is soil erosion. The major areas of sediment erosion are in the marine clay areas. In the last ice age extensive areas of Norway were submerged and left silt and clay deposits in these areas. These are very easily eroded and are wearing away under the pressure of the Norwegian rivers. Because of the silt/clay soil of Norway and the global warming conditions, the softening soil is becoming much loser and susceptible to land slides and during much more frequent floods, land is slowly washing away. The major cause of this is global warming. Due to the melting of glacier ice on the mountains in Norway, the rivers are rising and washing away more and more sediment. In my opinion, if we worked on fighting pollution and other green house gases these glaciers wouldn't be melting and Norway wouldn't be losing more and more land by the year.
