Detailed explanation-1: -Of all the species that have existed on Earth at some point over the past 3.5 billion years, over 95% have gone extinct. That’s part of the natural process of evolution. The difference is that the current level of extinction is almost solely caused by one particular species-humans.
Detailed explanation-2: -The current extinction crisis is entirely of our own making. More than a century of habitat destruction, pollution, the spread of invasive species, overharvest from the wild, climate change, population growth and other human activities have pushed nature to the brink.
Detailed explanation-3: -The rapid increase in global temperatures in the past 100 years, combined with ocean acidification, heavy metal contamination, and ozone depletion caused by human activities have caused 99.9% of all of Earth’s species to go extinct.
Detailed explanation-4: -Extinction Rates Regardless, scientists agree that today’s extinction rate is hundreds, or even thousands, of times higher than the natural baseline rate. Judging from the fossil record, the baseline extinction rate is about one species per every one million species per year.
