Native ecosystems are natural environments that have developed over long periods without significant human interference. They consist of local plants, animals, and microorganisms that have adapted to the specific climate and soil conditions of a region. These ecosystems are crucial for maintaining biodiversity and supporting the overall health of the planet. Preserving native ecosystems is important because they provide essential services, such as clean air and water, pollination of crops, and habitat for wildlife. Examples of native ecosystems include tropical rainforests, grasslands, and wetlands. Protecting these areas helps ensure the survival of various species and the balance of natural processes.
