But, as scientists estimate, we are currently losing species 1,000-10,000 times faster than that, which means that literally tens of species are vanishing from the face of the Earth every day. 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. Another way the extinction rate can be given is in million species years (MSY).
