Scientists warn of flowering plant extinction risk

A comprehensive study of Earth's flowering plants has revealed that more than half of the species assessed are threatened with extinction, prompting a stark warning from scientists about the consequences for humanity. The research, published in the journal Plants, People, Planet, found that 45% of flowering plant species are at risk, with an estimated 77,000 species currently threatened. This figure is based on an analysis of 328,565 species, representing the most complete assessment of the world's flora to date. The study highlights that tropical regions, particularly in South America, Africa, and Southeast Asia, are the most affected, with deforestation and habitat loss being the primary drivers. The loss of flowering plants is critical because they form the foundation of most terrestrial ecosystems, providing food, medicine, and oxygen. The researchers warn that the decline could disrupt pollination, food chains, and carbon storage, directly impacting human well-being. The study's lead author, Dr. Eimear Nic Lughadha, noted that the findings underscore the urgent need for conservation efforts to protect plant diversity. The next steps, according to the scientists, involve prioritizing conservation actions for the most threatened species and habitats, as well as addressing the underlying causes of plant extinction, such as agriculture and urbanization.
