September 29, 2010 Study: 22% of Plant Species Face Extinction ------------------------------------------- A new study is warning more than a fifth of the world’s plant species are at risk of extinction. The Sampled Red List Index says 22 percent of almost 4,000 species are threatened, with human-induced habitat loss the cause in over 80 percent of the cases. Stephen Hopper of London’s Royal Botanic Gardens said, "We cannot sit back and watch plant species disappear—plants are the basis of all life on Earth, providing clean air, water, food and fuel. All animal and bird life depends on them, and so do we." .
