How do forests affect water quality?
In a recent study done by the World Bank in collaboration with WWF, it was discovered that many big cities get their water-supplies from forest-catchment areas, as they capture and store water. Thus, maintaining a healthy forest ecosystem has become a necessity. Preserving our forests means reduction in land-slides, which translates to prevention of soil and sediment erosion. Forests also protect water-quality as they filter out pollutants, naturally, which is cost-effective.
