Some people are concerned about cutting down trees. After all, trees naturally clean the air so if a tree gets cut down, it is no longer able to clean the air, right? Well, yes and no.
Trees clean carbon dioxide out of the air but only to a certain extent. As a tree gets older, it cleaning ability gets diminished. And, eventually, it stops cleaning altogether.
When that happens, the tree becomes a liability. If that tree should catch on fire, all of the carbon dioxide that the tree absorbed will get released back into the atmosphere thus negating its air cleaning benefit.
So, whats the solution? Managed forests. Trees need to be harvested, when they become mature, and replaced with new saplings. That way we can maximize the benefits of trees while minimizing the liability.
