Workers at an alligator farm in Louisiana check each animal skin before sending it to companies that make luxury products. These products include boots, watch straps and handbags. Each skin has a yellow tag so officials can track where the product came from. Supporters say the system helps protect wild alligators because farmers raise young animals and follow rules for trade. Many products are sold in the global market for leather goods.

The program began many years ago when wild alligators almost disappeared from some wetlands. Farmers now collect eggs, raise young alligators and release some back into nature each year. Louisiana farms produce hundreds of thousands of animals every year, while millions still live in the wild. Scientists continue a study of alligators to understand how they affect wetlands. Some research shows that areas with many alligators may store more carbon in plants and soil. This information may help explain why alligators are important for the environment.
