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. The Royal Botanical Gardens in the UK led the report, which involved 210 scientists from 42 countries. The main cause of plant losses is the destruction of wild habitat to create farmland. Overharvesting of wild plants, building, invasive species, pollution and, increasingly, the climate crisis are also important causes of losses.
