Wilderness refers to natural areas that are largely untouched by human activity. These regions often include forests, mountains, deserts, and wetlands, where ecosystems thrive without significant interference. Wilderness areas are important for biodiversity, providing habitats for various species of plants and animals. In many countries, wilderness areas are protected to preserve their ecological integrity. This protection helps maintain clean air and water, supports wildlife, and offers opportunities for outdoor recreation. Organizations like the Wilderness Society advocate for the conservation of these vital landscapes, ensuring they remain available for future generations to enjoy.
