Tiêu đề F. Pierce 4.9 Summary ✅

5.2 Clearcutting - Forestry practice where all trees in an area are removed - Economically efficient for timber production - Severe environmental effects Drawbacks - The removal of tree roots, which hold soil in place, leads to increased wind and water erosion - Soil erosion causes sediment and nutrient runoff into streams, increasing water turbidity and potentially leading to algal blooms - Loss of shade from the tree canopy raises water temperatures, reducing dissolved oxygen levels and harming aquatic life - Forests absorb and hold water, so removing them leads to less water absorption and increased flooding risk - Clear-cutting destroys entire ecosystems, leading to habitat loss, fragmentation, and a reduction in biodiversity - Trees store carbon, and cutting and burning them releases this carbon back into the atmosphere. The loss of forests also reduces the planet's ability to absorb carbon dioxide Advantages - Clearcutting is often the most economically efficient and profitable method for harvesting large amounts of timber in the short term - It can be mechanized and performed quickly - Even-aged plantations are often managed for rapid growth and then harvested by clear-cutting
