However, this is not without untold harm to the environment. The damage includes habitat loss, pollution, and climate change, with the effects spanning the globe from the rain forests of Central Africa, Southeast Asia, and South America to the northern forests of Canada and Scandinavia. The effects of logging extend beyond just the felling of a swath of trees. Nutrients, water, and shelter for plants, animals, and microorganisms throughout the ecosystem are also lost; many life forms—both terrestrial and aquatic—are becoming endangered as forests vanish. Paragraph B Trees protect the soil beneath them; thus, tree loss can affect soil integrity. For example, the rain forest floor, home to myriad plant life as well as insects, worms, reptiles and amphibians, and small mammals, relies on a dense canopy of branches and leaves to keep it healthy and intact. The canopy prevents surface runoff by intercepting heavy rainfall so that water can drip down slowly onto the porous earth. Tree roots also stabilize the soil and help prevent erosion. In return, a healthy soil encourages root development and microbial activity, which contribute to tree growth and well-being. A major factor in logging-related soil damage comes from road building, with trucks and other heavy equipment compressing the spongy soil, creating furrows where water collects, and disrupting the underground water flow. Eventually, the topsoil wears away, leaving behind an infertile layer of rocks and hard clay. Paragraph C Logging can also damage aquatic habitats. Vegetation along rivers and stream banks helps maintain a steady water flow by blocking the entry of soil and other residue, and tree shade inhibits the growth of algae. Removing tre...
