The background extinction rate in mammals is thought to be one extinction event per million species per year, which is how it is measured. In other words, one in every 1,000 species (0.001) would become extinct every century. And now, according to the lists of the International Union for Conservation of Nature (IUCN), it stands at 1.8 species per year, which means that about 180 species would become extinct in a hundred years.
The Royal Botanic Gardens, Kew, in the United Kingdom, commonly known as Kew Gardens, produces the State of the World's Plants and Fungi report every year. The last report was the most devastating, as it found a correlation between the year a plant species was described and its level of threat on the IUCN list.
