“Tropical tree species could be in much bigger trouble than scientists had thought: A new study, which involved collaboration from dozens of researchers, suggests that at least 36 percent and up to 57 percent of all Amazon tree species are likely at risk of extinction, depending on future deforestation rates. If true, this information would raise the number of threatened plant species on Earth by about 22 percent.
“The research, which was published Friday in the journal Science Advances, combined spatial distribution models of the Amazon with both historical and projected data on deforestation to determine the conservation status of more than 15,000 Amazonian tree species, about two-thirds of which the authors considered rare species. The researchers used listing criteria from the International Union for Conservation of Nature (IUCN), which maintains a “red list” of threatened species on Earth, to decide which species should be considered in danger of extinction.” From: www.washingtonpost.com
GR: With the expected growth of our population and demand for meat and other products from forest soils, the threatened extinctions discussed in this article seem virtually inevitable.
