Biodiversity is vital for maintaining the health and balance of ecosystems on Earth. It ensures the resilience of ecosystems, allowing them to adapt to changes like climate shifts or natural disasters. Diverse species contribute to essential ecological processes such as pollination, soil fertility, and water purification. Biodiversity also supports food security, providing a variety of crops and livestock. Additionally, it contributes to human well-being through medicine, as many drugs are derived from plants and animals. The loss of biodiversity weakens ecosystems, leading to habitat destruction, species extinction, and destabilized environments, threatening the planet's overall sustainability.
