The Lacey Act is a U.S. law enacted in 1900 that aims to protect wildlife and plants by prohibiting the trade of illegally obtained species. It makes it illegal to import, export, or sell animals and plants that have been taken in violation of state, federal, or international laws. This act helps conserve biodiversity and ensures that natural resources are used sustainably. In addition to protecting wildlife, the Lacey Act also addresses issues related to invasive species and the illegal logging of timber. It requires importers to provide information about the source of their products, promoting transparency and accountability in the trade of natural resources.
