Main Idea of Biodiversity Importance
Listen to the following passage:
Today, our discussion will revolve around the role of biodiversity in maintaining healthy ecosystems. Biodiversity refers to the variety of life on Earth, encompassing different plants, animals, and microorganisms. It is crucial because it contributes to the resilience of ecosystems, allowing them to adapt to changes in the environment. For instance, a diverse array of species can ensure the availability of resources and help in the pollination of plants. Furthermore, biodiversity is essential for food security, providing a range of nutrients necessary for a balanced diet. Unfortunately, human activities such as deforestation, pollution, and climate change threaten biodiversity, leading to habitat loss and species extinction. Protecting biodiversity is not just an environmental concern; it is vital for human survival and well-being. Conservation efforts, sustainable practices, and education play key roles in preserving our planet's biodiversity for future generations.
