According to National park services (2017) The Burmese Python is one of the largest snake species on earth. However, the Burmese Pythons have become an invasive species in the Everglades. Ultimately, Pythons are a threat to biodiversity in the Everglades. Pythons eat too many species and plants in the Everglades, they can reach up to 20 feet, and they prey on a variety of wildlife in the Everglades.
To begin with Pythons are harmful to the biodiversity in the Everglades because they eat too many species and plants. For example a study by Newsela found 3 deers in just one snakes belly. In addition “Big animals have big appetites.” -Newsela, meaning they eat too much in order to survive, when the animals become scarce
As if there weren’t enough problems for scientists trying to save the Great Lakes Eco System. Many non-native species have entered the eco system and many of them are harmful. Every species in itself has played a role in the eco system. These non-native species make it increasingly difficult for the Great Lakes Eco System to be regulated.
These non venomous pythons have been documented to attack and constrict their owners which in turn have led handlers to release them illegally in the Everglades. Their existence and carnivore diet is concerning because these reptiles prey on native species that are endangered like the Key Largo woodrat and compete with threatened native species like the Indigo snake. Burmese pythons are part of the Federal Lacey Act and on the injurious list. This dictates that federal law does not allow transport across state lines nor foreign import of wildlife deemed injurious to the “health and welfare of humans, the interests of agriculture, horticulture or forestry, and the welfare and survival of wildlife resources of the
First of all, The snakes are destroying the ecosystem. According to, Burmese Python Not the Ideal Pet, " With no natural predators, these eating machines appear to be wiping out huge numbers of opossums, raccoons, and bobcats, as well as many bird species." This evidence shows that the pythons are eating and destroying all of these animals leading to early extinction which can affect all of the other species that rely on those animals the pythons are eating. Burmese python Not The Ideal Pet also states, "Tens of thousands of Burmese pythons are estimated to be living in the Everglades" This shows that thousands of snakes living on the everglades are destroying these poor animals that don’t deserve this.
Invasive species have the potential to harm their new environments. The release of Burmese pythons in South Florida is especially troublesome because the subtropical climate and the vast undisturbed habitats of the Everglades enable the species to thrive. Other large non-native snakes— such as the common boa (Boa constrictor), green anaconda (Eunectes murinus), yellow anaconda (Eunectes notaeus), and reticulated python (Python reticulatus)—have been observed in the wild in South Florida, but only Burmese pythons and common boas are known to be breeding. Burmese pythons were first reported as established in Everglades National Park (ENP) by Meshaka, based in part on specimens collected on the Main Park Road in the mid-1990s. Since then, the number of Burmese pythons captured or found dead in and around ENP has increased dramatically increased. From 2002 - 2005, 201 pythons were captured and removed or found dead. In 2006 - 2007 alone, that number more than doubled to
The invasive species, the Burmese Python has done irreparable damage to the Everglades National Park in Florida. A steady decline in mammals has been observed since the introduction of Burmese pythons occurred. Burmese pythons were first introduced into the United States as part of the pet trade which then led to the escape or intentional release out into the wild. The first notation of these species arriving was in the year 2000. However, within just eleven years this invasive species had done such a large amount of damage to Florida’s Ecosystem that many species had gone almost completely extinct.
There are invaders among us, they are not alien or human, but Burmese Pythons. Arguably one of the most beautiful and unique parts of nature remaining in the United States is rapidly being destroyed by the Burmese Python. It has enormously impacted the Everglades in a negative way. The beautiful indigenous animals have quickly disappeared and new predators surface as we dig deeper into the Everglades. This fierce animal is a constrictor, squeezing the life out of its prey. The Pythons tight grip sucks the life out of its prey and swallows it whole. “It sounded like a joke when news reported Burmese Pythons were invading the Everglades in 2000” states USA Today. Pythons are slithering their way through the Florida Everglades with a big appetite and a similar habitat as their original home in Asia. Now, they have marked their territory permanently and there may be nothing scientists can do in order to prevent this issue.
Should exotic snakes or other large reptiles be allowed as pets in Florida? Right now these escaped/released feral reptiles create an estimated $120 billion in environmental damage each year according to David Steen on Slates Animal Blog.

By using the pythons big size and massive jaw to swallow animals whole, the tens of thousand pythons are slowly, but surely, destroying the ecosystem in the Everglades. “A growing population of Burmese pythons— many pets turned loose by their owners when they became too big—is threatening the ecosystem of Florida’s Everglades. With no natural predators, these eating machines appear to be wiping out huge numbers of opossums, raccoons, and bobcats, as well as many bird species. Tens of thousands of Burmese pythons are estimated to be living in the Everglades, where they thrive in the warm, humid climate.” states a local newspaper article on how the pythons are ruining the

such changes as well as stop the introduction of exotic plant-life and animals into the Everglades.
The Everglades provides a healthy ecosystem for plants and animals but it has predators that endanger the wildlife that live there. Exotic pet owners often dump their invasive pet snakes that don’t normally have a habitat

The gorillas live mainly in coastal West Africa in the Congo, Zaire, Gabon, Equatorial Guinea and Cameroon. Gorillas live in the rain forest. They usually live on the ground but build nest in trees to sleep in. Gorilla troops keep a 15-20 square mile range which often overlaps the range of other troops. There are three different kinds of gorillas. The eastern lowland gorilla the western lowland and the mountain gorilla. They are herbivores and eat only wild celery, roots, tree bark pulp, fruit, stems of many plants and bamboo shoots. They spend nearly half their day eating.
One reason that these wild creatures shouldn’t be pets is because of the unexpected dangers they could release. People claim that their wild animals are “tame” and “safe”, but you can never predict what these creatures will do. According to an editorial by USA TODAY, “In 2009, a 2-year-old Florida girl was strangled by a 12-foot-long Burmese python, a family pet that had gotten out of its aquarium.” The family might have bought the snake, believing that it was harmless, but you never know what an animal, especially a wild one.
