Biological diversity is the variance found in all plant and animal species, as well as their genetic material and the habitats in which they live. There are three types of diversity: genetic diversity, species diversity, and ecosystem diversity. Biodiversity's value to humanity has been widely recognised in recent decades, and many would argue that diversity is necessary for the long-term development of various human activities. Biological diversity can help social and economic institutions thrive in ways that help the world's poorest people satisfy their food and nutritional needs while also preserving the cultural diversity of countries throughout the world.
