Tropical forests contain a vast array of plant and animal species that are not found anywhere else, and many of these species may have potential medical benefits for humans. For example, plants like the Madagascar periwinkle have been used to develop drugs to treat cancer, while the rosy periwinkle contains alkaloids that have been used to treat Hodgkin's disease and childhood leukemia. It's estimated that 25% of all modern drugs are derived from tropical forest plants. Therefore, preserving these forests is important not just for their ecological value, but also for their potential medical benefits.
