Ecosystem diversity refers to the variety of different ecosystems within a specific area or across the planet. This includes various habitats, such as forests, wetlands, grasslands, and oceans, each supporting unique communities of plants, animals, and microorganisms. The diversity of ecosystems contributes to the overall health of the environment and provides essential services, such as clean air, water, and food. Maintaining ecosystem diversity is crucial for resilience against environmental changes and human impacts. Healthy ecosystems, like coral reefs and rainforests, support biodiversity, which helps sustain life on Earth. Protecting these ecosystems is vital for preserving the planet's natural resources and ensuring a balanced environment.
