Extinction rates slow down from "summary" of The World Without Us by Alan Weisman
As more and more species disappear, the rate of extinctions begins to slow down. The initial wave of extinctions, caused by sudden changes in the environment or catastrophic events, tends to hit the most vulnerable species first. These are the ones with specialized diets, limited habitats, or small populations. Once these species are gone, the rate of extinctions starts to decrease. With fewer species left to go extinct, the pressure on the remaining ones is reduced. This allows some species to adapt to the changing conditions, while others find ways to survive in the absence of their former competitors or predators. Over time, the surviving species begin to fill the empty niches left by those that have disappeared, leading to a more stable ecosystem. As the ecosystem stabilizes, the rate of extinctions continues to slow down. The surviving species have had time to adjust to the new conditions, and the competition for resources is less intense. This allows them to thrive and reproduce, increasing their populations and reducing the risk of extinction.- It ultimately leads to a more resilient and balanced ecosystem. The loss of certain species may open up new opportunities for others to thrive, leading to a more diverse and dynamic environment. By understanding the process of extinction and adaptation, we can gain a deeper appreciation for the interconnectedness of all living things and the importance of preserving biodiversity.
