The introduction of an animal species into an environment other than one’s own can have serious consequences for the entire ecosystem. This invasive species will, in fact, completely upset the balance of the food chain, very often causing the disappearance or even the extinction of several other species, plant or animal.
The rabbit, an animal to keep at home!

While the rabbit is one of the sweetest and cutest pets imaginable, the fact remains that this little furball with long ears can be disastrous for the environment. once released into the wild.
The following story, which took place in 1859, perfectly illustrates the danger posed by rabbits introduced into an environment that is not theirs: Briton Thomas Austin, a hunter from South Australia, imports 12 pairs of rabbits one day.
Fifty years later, 600 million of these animals have colonized 60% of the territory at an average speed of 110 kilometers per year.
They reproduce quickly
Rabbits have proliferated exponentially, causing a real ecological disaster by causing soil erosion. It is because of the many holes and underground galleries that they dig all the time. The rabbits also caused a real agricultural disaster by devouring the crops.
And although many methods have been used to regulate their population, such as pausing huge fences of several thousand km. Or the introduction of predators like the fox. The problem is still relevant today, so quickly do they recur.
The giant African snail

For some time now, we have witnessed a new social phenomenon that consists of raising unusual animals and making them real pets. And what could be more unusual than a giant African snail?
Moreover, this species is raised, in fact, like a pet, just like a hamster or a white mouse.
Nevertheless, the “Lissachatina fulica,” of its scientific name, being extremely prolific in terms of reproduction, irresponsible management, such as releasing it into the wild, can have catastrophic consequences for the local flora fauna.
An animal to keep at home
Between September 2011 and January 2012, 35,000 “Lissachatina fulica” were thus able to be identified in the region of Miami, in the United States, far from their native Africa. The mollusk had already invaded, in the past, Miami as well as Guadeloupe, Martinique, and other Caribbean countries.
The species’ first appearance would also date from 1966 when a teenager had brought back in his suitcases three of these snails to establish them in a small terrarium in his room.
However, his grandmother, horrified at the sight of these gigantic mollusks, would have released them into the wild to get rid of them. From these three specimens were born, then, 18,000 individuals, whose eradication required, at the time, nine years and a million dollars, without having any real success.
Snakes are animals that should not be released into the wild.
The release of pet snakes into the wild has become a real problem as reptiles have become more popular with the general public.
Because if most of us adopt a dog or a cat, even a guinea pig, other people, much more unique, prefer to have a snake as a pet.
This bizarre attraction to these cold-blooded animals is fast becoming a fad, and as a result, more and more homes are found to house a custom-made vivarium for their pet snake.
These animals can become giants.
The problem arises when these snakes grow and become heavier and more greedy, which often forces families to dispose of them in the wild.
However, if these released animals are quite able to survive outdoors due to their voracious appetites, they can lead to the extinction of small species of local fauna, such as squirrels and hedgehogs.
But that’s not all, because these snakes, which are mostly constrictors, will continue to grow to reach frightening measurements. Because a python or a boa can easily reach 6 meters and weigh more than 100 kilos, without forgetting the impressive size that giant anacondas can reach.
If a released snake survives long enough to reach this size, it will naturally turn to larger prey, such as dogs or… humans, if they are unlucky enough to come across it.
Therefore, this kind of reptile owners needs to take it to the zoo or the competent authorities in their region to get rid of their bulky animal.
