Everything is tied to everything else like a spider web. When you move one piece, it affects other parts. It is up to us to make a decision now as to what our future forests will be. Fire can take waste out of the forest, but uncontrolled fires can be bad and cause a loss of future income from your forest. If you keep taking the best trees out of the forest and leave the bad trees, the forest's value is decreased, which is called high grading.
Damaged trees become more open to insects and disease.
You need to balance or care for what you take from the forest so the future forest increases in quality. As cities grow in what is called sprawl, land is cleared that results in a loss of forest and agricultural land and a loss of habitat, or places for animals to live. The forest provides homes, food, jobs, and a place to play, and it cleans water. The trees are pretty in the spring and fall and that makes people want to come and see the forest. The forests are a renewable resource.
