Biodiversity, or biological diversity, encompasses the variety of life on Earth, from genes to entire ecosystems. It's crucial for healthy ecosystems, providing essential resources like food, water, and medicines. Loss of biodiversity threatens human health and well-being, impacting global nutrition, traditional medicines, and potentially increasing zoonotic diseases. Conserving biodiversity is crucial for building resilient food systems, combating climate change, and maintaining ecosystem services like pollination and soil fertility.
