Only a small fraction of plant species in the world's tropical forests have been closely examined for their potential use by humans. Some estimates suggest that less than 1% of the approximately 300,000 known plant species in tropical forests have been screened for bioactive compounds or other useful properties. This underscores the urgent need for continued exploration and conservation efforts in these important ecosystems.
