What happens to populations when faced with environmental change?

When populations are faced with environmental change, they may experience shifts in size, distribution, and genetic diversity. Some individuals may adapt to the new conditions, while others may migrate to more suitable habitats or face increased mortality rates. Over time, these changes can lead to evolutionary shifts or even extinctions, depending on the severity and nature of the environmental change. Overall, the resilience of a population largely depends on its adaptability, genetic variability, and the rate of environmental change.
