<human>:  How does wood rot and what can I do to prevent it?
<bot>: Wood rot is caused by fungi that feed on wood, breaking it down into cellulose which produces stick and unappealing odors. To prevent wood rot, use preservatives, paint or varnish, and keep the wood dry by ensuring proper ventilation and controlling moisture in the surrounding environment. If the rot has already begun, you can use a fungicide to stop it from further damaging the wood.
