A more thorough explanation:

Definition: The Lacey Act is a law that was passed in 1900. It makes it illegal to transport animals or plants that are endangered or harmful to the environment across state lines.

For example, if someone catches a fish that is endangered in one state and tries to sell it in another state, they would be breaking the Lacey Act. Another example would be if someone tried to transport a plant that is harmful to the environment from one state to another.

The Lacey Act helps protect endangered species and prevent harmful plants and animals from spreading to new areas. It is important to follow this law to help preserve our natural resources.
