Protecting watersheds is crucial because they play a vital role in supporting biodiversity and providing essential water resources. Watersheds are areas of land where all the water that drains off flows into a common body of water, such as a river or lake. This ecosystem supports a wide variety of plants and animals, many of which are interdependent. The health of a watershed directly influences water quality and quantity, which are essential for both ecological balance and human needs.

In addition, healthy watersheds help to filter pollutants, maintain water temperatures, and promote habitats for aquatic and terrestrial species. They are also essential in the water cycle, facilitating the replenishment of groundwater and surface water resources that people and wildlife rely on.

While other options such as reducing soil erosion and managing stormwater runoff are important benefits of healthy watersheds, the fundamental role they play in biodiversity and the provision of clean water resources is paramount. This overarching significance highlights the critical need for their protection and sustainable management.
