Extreme environments are characterized by very low population densities. They are generally relatively inaccessible and tend to be viewed as inhospitable to human habitation. Despite this, they provide numerous opportunities for settlement and economic activity.

Agriculture can be sustainable, as long as the carrying capacity of the land is not exceeded. In some areas, this means migrating with herds rather than practising sedentary farming. Tourism offers some possibility for sustainable economic activity, especially in hot areas. However, water shortages may be an issue. Mineral development is unsustainable but can be used as a catalyst for economic development.

Answers should show a good understanding of sustainability.
