40% of world’s plant species at risk of extinction | Plants | The Guardian
Two in five of the world’s plant species are at risk of extinction as a result of the destruction of the natural world, according to an international report.
Plants and fungi underpin life on Earth, but the scientists said they were now in a race against time to find and identify species before they were lost.
These unknown species, and many already recorded, were an untapped “treasure chest” of food, medicines and biofuels that could tackle many of humanity’s greatest challenges, they said, potentially including treatments for coronavirus and other pandemic microbes.
More than 4,000 species of plants and fungi were discovered in 2019. These included six species of Allium in Europe and China, the same group as onions and garlic, 10 relatives of spinach in California and two wild relatives of cassava, which could help future-proof the staple crop eaten by 800 million people against the climate crisis.
