What do conservation agents do?

Explanation:

they conserve or simply implying they preserve the object or the material used on to make them last for longer or even in other cases increase production so simply they add some nutrients to the object that makes it last longer without casualties

Conservation Officers (Fish and Game Wardens) can be found patrolling the lands and waters of the state day and night. Most people will tell you that enforcing the game and fish laws is their primary responsibility, but the job doesn’t stop there. In addition to enforcement, the conservation officer educates the public about wildlife and wildlife management, conducts wildlife surveys, captures “problem animals,” investigates wildlife damage to crops and property, assists in wildlife relocations and helps to develop new regulations.”
