Ecological crisis
Encyclopedia : E : EC : ECO : Ecological crisis
An ecological crisis occurs when the environment of a species or a population changes in a way that destablizes its continued survival. There are many possible causes of such crises:
- It may be that the environment quality degrades compared to the species' needs, after a change of abiotic ecological factor (for example, an increase of temperature, less significant rainfalls).
- It may be that the environment becomes unfavourable for the survival of a species (or a population) due to an increase pressure of predation (for example overfishing).
- Lastly, it may be that the situation becomes unfavourable to the quality of life of the species (or the population) due to raise in the number of individuals (overpopulation).
