Gaberiel Pacheco uses to hunting American crocodile. Now he protects them because of the word conservation spread throughout the younger. The crocodile is the top species in the in an environment. If you removed the top predator from the food chain, the prey will run wild. The large declined of the population of the crocodile is because of the illegal hunting. Clara Sierra, a biologist for the regional environmental authority (known as CVS) and also a member of the IUCN's Crocodile Specialist Group, describes this initial meeting between the hunters and conservationists as "the first step toward building a relationship of confidence." She is trying to spread the word conservation, so the people will not illegal hunt or kill.
