The Fish and Wildlife Services was established in 1940. They Created the Fish and Wildlife Services to protect and conserve, wild life, plants, fish, and their habitats. So the american people could benefit from this.There are some regulations the U.S Fish and Wildlife Service have. If you want to import or export specimens across the U.S. border you have to get a licence from the U.S. Fish and Wildlife Agency. There is the Marine Mammal Protection Act. This law is for the protection of marine animals; no persons is to sell, import, or purchase, unless the animal is specially exempt. There is also the Endangered Species act. This law is probably americas most known wildlife protection law. This law proctects animals and plants that are endangered or could be endangered in the near future. It is against the law to export, import, purchase, or sell any species on the list of endangered speices list.
A Prime example of an impact on humans, and animals, would be the wolf that is on the endangered species list. With the wolves being on the list it really affects farms, and hunters; becasue wolves are killing livestock and hunting game. But is also sent population lower to the wolf into negative effects.
