One in five of the world’s plant species is threatened with extinction, according to the first global assessment of flora, putting supplies of food and medicines at risk.
But the report also found that 2,000 new species of plant are discovered every year, raising hopes of new sources of food that are resilient to disease and climate change. New finds in 2015 included a giant insect-eating plant first spotted on Facebook and a 100-tonne tree hidden in an African forest.
The State of the World’s Plants report, by experts at the Royal Botanic Gardens Kew, reveals that there are currently 390,000 species of known plants, with more than 30,000 used by people. However, more than 5,000 species have invaded foreign countries and are causing billions of dollars of damage every year.
