Preserving old-growth forests provides numerous ecological benefits, such as maintaining biodiversity by serving as habitats for a variety of plant and animal species, including endangered ones. These forests also play a crucial role in carbon sequestration and storage, helping to mitigate climate change. Additionally, old-growth forests contribute to soil health and water quality, as well as provide essential ecosystem services like regulating water flow and preventing soil erosion. Preserving these forests helps to protect delicate ecosystems and maintain a healthy environment for future generations.
