In 265, 571 plants be wiped out

deforestation in Madagascar has led to the extinction of many plant species.
the mid-18th century, humans have caused an average of more than two plants to disappear from the planet each year, according to a study published today in Nature- Ecology and Evolution. This is the first comprehensive study to map global plant extinction.
best guess in the botanical world is that fewer than 150 species are extinct, but this is based on the Red Book of Endangered Species, which is known to cover only a small number of plants. The true figure appears to be four times that of 571 plants that died out between 1753 and 2018. A Swedish and British team of researchers came up with the figure after analysing an previously unresolted database at the Royal Botanic Gardens.
destroyed species include Chilean sandalwood and St. Hellerna olive trees. The former is found only on a group of islands in the Pacific Ocean, while the latter lives only on islands named after them.
plants are dying out 500 times faster than the earth's historical background. The so-called background velocity refers to the rate of natural extinction of plants before human influence occurs.
, however, Aelys Humphreys, of the Royal Botanic Gardens, said that even if 571 species of plants were extinct, it could be lower than the actual figure. "We're sure that number is undervalued." Humphreys said that because some areas of the world's biodiversity have been studied very little, and the number of plants has been reduced to such a low level that it is considered a "functional extinction."
plants are far more extinct than birds, mammals and amphibians. This is what the researchers expected when they considered the plant as a whole to have more species. However, the geographical location of animal and plant extinction is strikingly similar. Island species are inherently vulnerable and have been particularly hard hit. The same is said of species living in tropical or Mediterranean climates, which don't look so bad just because they have a rich and diverse life. Of these, Hawaii is more extinct than anywhere else in the world, with 79 species extinct here alone. Other hotspots include Brazil, Australia and Madagascar
