Quick question Herping enthusiasts enjoy spending their days in nature, searching for amphibians and reptiles. While looking for snakes and frogs seems like an enjoyable pastime, many people who spend their time herping are actually completing important research. Much of this research has to do with declining amphibian and reptile populations. They also investigate the causes of these declining populations. One activist from Arizona, Leonardo Dolmage, has used his experiences to complete important research about the effects of human impacts on the environment.

Outdoor activities like herping are popular in Arizona. Herping is only one activity that adventurers enjoy. While outdoor activities like hunting, fishing, and camping result in positive experiences for travelers, they can also have negative effects. Due to increasing human activity in the state of Arizona, many species have lost their habitats. When tourist companies set up locations, some species are forced to find new places to live. When species move, they can disrupt their new environments. Even herping can have negative consequences. Some herpers go to great lengths to find amphibians and reptiles. Sometimes, their searches lead to trampling on or polluting natural environments.

Many people who enjoy outdoor activities are responsible. However, others are not aware of how their activities impact the environment. Sometimes those enjoying outdoor activities leave garbage behind. Other times, they travel long distances to visit attractions, putting more carbon dioxide into the atmosphere. Recently, herpers have noticed low populations of some amphibians and reptiles in popular tourist areas. When one species becomes extinct, it can disrupt the entire ecosystem. It is important for humans to put nature first. Otherwise, their activities can destroy natural ecosystems. While herping and other activities are fun, if they disrupt a snake or frog's home, they are not worth it.
