Answer: Leaving trees that are not as economically valuable will help biodiversity because although they are not very expensive to us, they are very valuable to some other organisms.
Explanation: The left over trees can provide shelter for organisms who maybe lost their’s because it was one of the trees that got cut down, or their ecosystem could have gotten polluted in an entirely different area. Only cutting down some trees, especially if they are the more valuable ones, will certainly sustain the logging business while still ensuring the environment stays taken care of.
