Prohibits governmental entities from granting legal personhood to a variety of objects

HB 721 prohibits Missouri governmental entities (like courts, legislatures, or local authorities) from granting or recognizing "legal personhood" for specific categories. It defines legal personhood as the legal rights and obligations under Missouri law and explicitly bans government recognition for artificial intelligence, inanimate objects, bodies of water, land, real property, atmospheric gases, astronomical objects, weather, plants, nonhuman animals, and nonhuman species. This bill directly affects how Missouri government interacts with these entities, preventing them from being treated as legal persons with rights or obligations. The policy change is a clear restriction on government actions, not a new right for the affected categories.
