What is the most important role of the ecosystems of the Andes? Keep the environment stable and reduces air pollution Reduce the chance of floods, desertification, and landslides Regulate the availability of freshwater All of the above

The ecosystems of the Andes play a crucial role in regulating the availability of freshwater, a vital resource for millions of people. Glaciers and high-altitude lakes act like natural reservoirs, storing water and releasing it gradually during dry seasons. This regulation sustains agriculture and drinking water supplies for communities both within and beyond the mountain ranges. Additionally, the diverse flora and fauna of the Andes contribute significantly to the overall environmental stability. They help mitigate natural disasters like floods and landslides by maintaining soil integrity and controlling water runoff, all while sequestering carbon and reducing air pollution levels. It's a fantastic ecosystem that's hard at work keeping our planet habitable!
