Cheetahs

There’s nothing unnatural about the process of extinction or, for that matter, about disturbance to Earth’s ecosystems. More than 99 percent of all species that ever existed have become extinct over a period of more than 3.5 billion years of evolution, and ecosystems have expanded or receded in the wake of climate changes and natural disturbances.

Of course, the overarching difference between extinctions of the past and those
of the present can be summed up in one word: humans. Never before on our planet has one species been responsible for such a massive decline of global biodiversity.
