For example, Machakos in Kenya, whose population rose to 250,000 – with accompanying resource over-exploitation, denuded hillsides and soil erosion – actually improved when its population rose still further.
The relative economic efficiency of driftnets when used to fish dispersed resources has also been taken to suggest that resource over-exploitation may occur more easily.
Be it too many people chasing too few resources, the over exploitation of natural assets, declining returns from land and sea, climate is seen to play a major part.
Individual species are being obliterated by habitat loss and degradation, invasive species, the spread of pollution and disease, climate change and the over exploitation of resources.
In this present scenario, the increasing population is leading to the over exploitation of resources resulting to their decline.
However, because all arctic regions have in recent times come under western science-based state management systems and an increase in human population numbers, the story that is more often heard concerns resource shortage, over-exploitation, and the danger of species extinction (e.g. Macpherson 1981; Theberge 1981; Ludwig et al. 1993; Fienup-Riordan 1999).
Increasing rate of urbanization and industrialization has lead to over exploitation of natural resources such as river sand and gravels, which is giving rise to sustainability issues.
In a global context where the need for quality housing is increasing with improved standard of living and growing population, the over exploitation of natural resources as building materials is becoming a serious problem.
We referred in Section 2.2 to the danger of ecological damage resulting from the over exploitation of groundwater resources, particularly fossil water, i.e. water of ancient origin which cannot be replaced.
Limited access to food obliges people to switch to poorer diets and resort to other harmful coping mechanisms: children, in particular girls, are taken out of school and forced to work; families fall into debt, sell their assets, resort to over exploitation of natural resources, or are forced to migrate in search of income, ultimately falling into destitution.
