- How many species are we losing? | WWF
These experts calculate that between 0 01 and 0 1% of all species will become extinct each year If the low estimate of the number of species out there is true - i e that there are around 2 million different species on our planet** - then that means between 200 and 2,000 extinctions occur every year
- How Many Species Are There on Earth and in the Ocean?
This approach was validated against well-known taxa, and when applied to all domains of life, it predicts ~8 7 million (± 1 3 million SE) eukaryotic species globally, of which ~2 2 million (± 0
