The Brazilian tortoise must not be released into the wild. When a creature is introduced into a new environment, if it is out of human control and becomes wild, it is easy to spread wildly under suitable climate, soil, water and transmission conditions, forming a large-scale single-superior community, destroying local animals and plants, and even endangering the survival of local endangered animals and plants, thus losing biodiversity. These invasive species must have natural enemies to control their population in their original ecosystem, but there is usually no such control mechanism in the new environment, so these species may be flooded.

In Hongkong and Taiwan Province, scientific investigation proves that the Brazilian tortoise is a veritable "ecological killer". Less than 20 years after its introduction to Taiwan Province, the Brazilian tortoise has settled and bred in Taiwan Province, becoming the most common turtle in Taiwan Province. In the wild, the Brazilian tortoise will prey on a large number of eggs and tadpoles of small fish, shellfish and frogs, causing havoc in the local ecological water. The Keelung River in Taiwan Province has long been occupied by Brazilian turtles and pipa rats. Brazilian tortoises are fertile at the age of 2, while native tortoises don't mature sexually until they are seven or eight years old, which is one of the reasons why Brazilian tortoises are cheap. The Brazilian tortoise has low requirements for food and living environment, strong adaptability to the environment, fast growth, strong reproduction and fierce predation. If released at will, in the long run, because it has no natural enemies, it will enter rivers and lakes in large numbers and compete with local turtles for food, which will threaten the survival of local turtles and related species and cause great damage to the original ecological chain.
