Final answer:
Clear-cutting is a concern for the environment because it destroys habitats, kills animal life, contributes to soil erosion and water pollution, and disrupts ecosystems. Replanting after clear-cutting helps but cannot fully address the damage caused.
Step-by-step explanation:
Clear-cutting is still a concern for the environment because it destroys entire habitats, kills animal life, and contributes to soil erosion and water pollution. When a forest is clear-cut, it removes the diverse ecosystem that supports numerous species of plants and animals. The destruction of habitats can lead to the extinction of species and disrupt the balance of ecosystems.
Additionally, the removal of trees results in soil erosion and the loss of nutrients, making it difficult for forests to regenerate. Clear-cutting can also lead to water pollution through sediment runoff and increased acidity in dammed rivers. Government regulations requiring replanting after clear-cutting help mitigate some of the environmental impacts but cannot completely address the damage caused by this practice.
