Biodiversity, or biological diversity, refers to the variety and variability of life forms on Earth. It encompasses the diversity of species, genetic variation within those species, and the variety of ecosystems in which they exist. Biodiversity is essential for ecosystem resilience, providing crucial services such as pollination, nutrient cycling, and climate regulation. It contributes to the stability of ecosystems and their ability to withstand environmental changes. Biodiversity is typically categorized into three levels: species diversity (the number of different species), genetic diversity (the variation in genes among individuals within a species), and ecosystem diversity (the range of different habitats and ecological processes). The loss of biodiversity due to factors such as habitat destruction, pollution, and climate change poses significant challenges to the health of the planet and the survival of various life forms, including humans. Protecting biodiversity is vital for maintaining ecosystem functions and supporting livelihoods, making it a key focus for conservation efforts globally.
