Yes, it is widely accepted that over 99% of all species that ever lived on Earth are now extinct. This staggering statistic highlights the natural process of evolution and extinction that has been occurring for billions of years. The Earth's history is a long story of species emerging, evolving, and sometimes vanishing, paving the way for new life forms. This perspective underscores the fragility of life and the importance of conservation efforts to protect the biodiversity we still have today.

FAQs & Answers

  1. What does it mean that 99% of species are extinct? It means that the vast majority of species that have ever lived on Earth no longer exist, reflecting the natural processes of evolution, environmental change, and extinction over billions of years.
  2. Why have so many species gone extinct? Species extinction occurs due to factors such as environmental changes, natural disasters, competition for resources, and sometimes human activities disrupting ecosystems.
  3. How does extinction impact biodiversity? Extinction reduces biodiversity, which can weaken ecosystem stability and resilience, making conservation efforts vital to protect remaining species.
