The concept of biodiversity encompasses not only the variety of species within an ecosystem but also the genetic variability among individuals and the diversity of ecological processes. Recent studies suggest that high biodiversity acts as a buffer against environmental disturbances, such as climate fluctuations or disease outbreaks. This resilience arises because a richer array of species increases the likelihood that some will possess traits enabling survival under changing conditions. However, human activities, including habitat fragmentation and overexploitation, are accelerating biodiversity loss at rates unprecedented in geological history. Conservation efforts, therefore, must prioritize the preservation of entire ecosystems rather than focusing solely on charismatic megafauna, as the intricate interdependencies among species often determine the stability of the whole system.
