The environment plays a crucial role in longevity. For example, one of the environmental factors is air quality. During the lockdown, mortality in Europe decreased thanks to the reduction of air pollutants from vehicles and industries (. Another environmental factor that can prolong longevity is living at higher elevations.
The term longevity refers to the ability to live significantly longer than the typical lifespan of a given species. It is usually understood as the average life expectancy that can be achieved under optimal conditions.
