Biodiversity plays a crucial role in pharmaceuticals due to the wide variety of plant and animal species that contain bioactive compounds with potential medicinal properties. These natural compounds have been used in the development of many important drugs, such as antibiotics, anti-cancer agents, and painkillers. The diverse array of species in different ecosystems provides a rich source of unique chemical compounds that can be studied and utilized in the pharmaceutical industry for the discovery and development of new medicines. This highlights the importance of conserving biodiversity not only for ecological reasons but also for potential medical breakthroughs.
