Biodiversity, the variety of life on Earth, plays a critical role in maintaining ecological
balance. Ecosystems with high biodiversity tend to be more resilient, adapting to changes and
recovering from disturbances. Conversely, ecosystems with low biodiversity are vulnerable to
collapse. Factors such as habitat destruction, climate change, and pollution are driving a rapid
decline in biodiversity. Scientists emphasize the need to preserve biodiversity as it underpins
essential ecosystem services like pollination, water purification, and climate regulation.
