Introduction

´╗┐To what extent should cold environments to be considered as fragile? How far does this affect their development?????????????????????????? A fragile environment is a biome that is under threat from change, damage or unsustainable use. Most impacts will be long-lasting due to the inability of the area to recover easily due to extreme cold because things never decompose nor grow quickly. There is no denying whether or not cold environments are vulnerable to interference. The slow rate if of plant growth means that any disruption takes 50 years to correct. ...read more.

Middle

Plants therefore have to adapt to meet the needs of these challenges. The food chain is very short, and species have to also adapt to the harsh conditions, meaning the populations are low. It is very fragile as any interference to a certain species will wipe out many others in the food chain. However whether they be exploited successfully is the key question. For the reasons above it is crucial that the development of these areas is managed wisely. ...read more.

Conclusion

The 5 years of design meant it could navigate through Alaska, avoiding interference of Caribou migration pathways. It has been adapted by elevation- heat from the line does not thaw the permafrost leading to no subsidence. Caribou can also pass under the elevated areas. Thick insulation allows the pipeline to pass under the ground so that caribou can travel on top, it also allows for further development as roads can be built on top providing infrastructure. This shows that the large extent of fragility experienced in Alaska can be overruled by careful engineering allowing expensive but possible development of such areas. ...read more.

    The largest feature of glacial erosion is most certainly the U-shaped valley, or glacial trough. This is a smooth valley with steep sides, flat floor and a fairly straight channel. The Great Langdale Valley in the Lake District National Park was formed via abrasion where a glacier fed into a
