www.smh.com.au: "Worldwide demand for herbal remedies is threatening natural habitats and endangering up to a fifth of wild medicinal plant species, which are being harvested to extinction, a science magazine says.
A study to be published later this year by the World Wildlife Fund warns that between 4000 and 10,000 plants may be at risk.
'It's an extremely serious problem,' the study's author, Alan Hamilton, told New Scientist magazine, in its latest issue.
The findings are based on an analysis of the number of species at risk on the World Conservation Union's red list of threatened plants."
