An ecological crisis occurs when changes to the environment of a species or population destabilizes its continued survival. Some of the important causes include: Degradation of an abiotic ecological factor (for example, increase of temperature, less significant rainfalls) Increased pressures from predation.
Why is ecological crisis occurred in modern times what are its effect?
Explanation: These all crises result in global increase of temperature due to global warming which affect human and animals life along with increasing the rate of glaciers melting. Also, it result in environmental changes which is why many plants and animals species are close to extinction.
