Biodiversity and extinction

Biodiversity refers to the variety of life on Earth, including all species of plants, animals, fungi, and microorganisms, along with their habitats and ecosystems. It is essential for maintaining healthy environments and supporting life systems. Extinction occurs when a species completely disappears, often due to habitat loss, climate change, pollution, overhunting, or invasive species. High rates of extinction threaten biodiversity, disrupting ecosystems and reducing their resilience. Protecting biodiversity helps ensure ecological balance, benefits human well-being, and preserves the natural heritage for future generations.
