Why is wood cutting business halal as it destroys nature and cutting of trees.

It depends on the nature and need of the society but itself cutting trees for the need is allowed. Same as selling knife is not haram itself because the main purpose of knife is to use it for household works. Doing anything without purpose and reason is not allowed in Islam. Also we have to evaluate the purpose if it’s consequences are more severe than its need then as an obligatory precaution it must not be done.
