Major mass extinction events that spanned millions of years wiped out 75 to 90% of species on Earth, with causes ranging from asteroids to major changes in Earth's carbon cycle. Humans have also contributed to modern-day extinction through unsustainable use of resources, energy consumption, climate change, invasive species, and disease spread via trade.

Summary
Mass extinction events spanning millions of years wiped out 75-90% of all species each time, with causes ranging from asteroids to global warming and changes in the Earth's carbon cycle. The most studied extinction event occurred 66 million years ago, marking the end of non-avian dinosaurs and the emergence of mammals and birds.
