Here's why:

* Adaptation: Organisms are capable of adapting to environmental changes. This can happen through natural selection, where individuals with traits better suited to the new environment survive and reproduce more successfully, passing those advantageous traits to their offspring.

* Evolution: Over long periods, adaptations can accumulate, leading to significant evolutionary changes. This can result in the emergence of new species or the modification of existing ones to better suit the altered environment.

* Resilience: Many species have inherent resilience, meaning they can tolerate some level of environmental change. This resilience may stem from a broad diet, diverse habitats, or other factors that give them flexibility.

Example:

* The peppered moth is a classic example of adaptation. During the Industrial Revolution, pollution darkened tree bark. Light-colored moths were more visible to predators, while darker moths had an advantage. Over time, the population shifted to have a higher proportion of dark-colored moths.

While environmental change can lead to extinction, it is not an automatic consequence. The ability of organisms to adapt and evolve is a crucial factor in determining their survival.
