Biodiversity plays a crucial role in pharmaceuticals due to the vast array of unique plant and animal species that can be a source of potential therapeutic compounds. Many pharmaceutical drugs are derived from natural sources, such as plants, marine organisms, and microorganisms, which highlights the importance of preserving biodiversity for future drug discovery and development. By protecting biodiversity, we can continue to explore and utilize the rich genetic and chemical diversity found in nature to develop new medicines and treatments for various diseases.
