ecological crisis

An ecological crisis occurs when changes to the environment of a species or population destabilizes its continued survival. Some of the important causes include: 1-Degradation of an abiotic ecological factor (for example, increase of temperature, less significant rainfalls); 2-Increased pressures from predation; 3-Rise in the number of individuals (i.e. overpopulation). The evolutionary theory of punctuated equilibrium sees infrequent ecological crises as a potential driver of rapid evolution. Because of the impact of humans on the natural environment in the recent geological period, the term ecological crisis is often applied to environmental issues caused by human civilizations such as: the climate crisis, biodiversity loss and plastic pollution which have emerged as major global challenges during the first few decades of the 21st century.
