Discuss advantages and disadvantages of clearcutting (at least 2 each)
Advantages include efficient harvesting, regeneration of sunlight-demanding species, and creation of wildlife habitats. Disadvantages include soil degradation, erosion, nutrient loss, and negative visual impact.
Describe the risks of tree climbing and how to reduce them

Discuss advantages and disadvantages of wildfires
Wildfires can destroy forests, homes, and wildlife habitats. However, they can also help regenerate ecosystems and remove old vegetation. Some species depend on fire for growth. But uncontrolled fires are dangerous and costly.
Compare hand tools and power tools (at least 4 sentences)
Hand tools offer more control and precision but require more effort. Power tools are faster and more efficient but can be less precise and more dangerous. Both are essential depending on the task.
