Which of the following is a result of healthy forests?

Healthy forests contribute to greater resistance to forest pests due to a combination of factors that promote ecosystem balance and resilience. In a healthy forest, there is often a diverse array of tree species and ample undergrowth that creates a balanced ecosystem. This biodiversity can deter the spread of specific pests, as many forest pests may be more impactful on monocultures (areas where a single species dominates), which are not as resilient to pest invasions.

Additionally, healthy trees are typically stronger and more capable of defending themselves against pests. They can produce natural chemicals that deter insects and support a variety of wildlife that preys on these pests, further contributing to pest control within the ecosystem.

In contrast, scenarios such as increased soil degradation or lower biodiversity do not arise from healthy forests; rather, they are potential consequences of unhealthy forest practices or environmental degradation. Thus, the state of being a healthy forest correlates directly with its ability to resist pest infestations effectively.
