Biotechnology and conservation: the role of genetic technologies in preserving ecosystems and endangered species

Earth’s biodiversity is under unprecedented pressure due to human activities such as habitat destruction, pollution, and climate change. In this context, biotechnology has emerged as a key tool in the conservation of endangered species. Through genetic engineering techniques, it is possible to improve preservation strategies, contributing to the maintenance of ecosystems and global biodiversity.

Genetic engineering involves modifying the DNA of an organism to introduce or alter specific traits. This process makes it possible to create species with characteristics that may be essential for their survival, especially in the case of endangered species. Among the main applications of genetic engineering in conservation are the enhancement of genetic diversity, disease resistance, and adaptation to new habitats.

One of the biggest challenges faced by endangered species is the lack of genetic diversity. Small and isolated populations tend to suffer from inbreeding, which reduces the vitality of individuals and increases their vulnerability to disease and reproductive failure. Through genetic engineering, it is possible to introduce genetic variability, reducing these risks and increasing the chances of species survival.

Moreover, endangered species are often more susceptible to infectious diseases that can wipe out entire populations. Genetic engineering can produce individuals with greater resistance to specific pathogens, helping to mitigate the threat of outbreaks that could eliminate the last remaining populations. Additionally, some species face changes in their traditional habitats due to climate change. Through genetic engineering, it is possible to endow organisms with traits that allow them to better adapt to new environmental conditions, such as rising temperatures or resource scarcity.

Practical cases of genetic engineering applied to conservation

There are several examples in which genetic engineering has shown promising potential for the conservation of endangered species. One of the most well-known cases is that of the northern white rhinoceros, which is functionally extinct in its natural habitat. With only two females alive, scientists are using in vitro fertilization (IVF) techniques and stem cells to create hybrid embryos, with the southern white rhinoceros serving as a surrogate mother. This effort has been key to trying to revive the species and prevent its complete disappearance.

Another relevant case is that of the Florida panther, whose population suffered severe inbreeding problems, affecting its health and reproductive capacity. To increase genetic diversity, geneticists introduced genes from Texas cougars, which helped revitalize the population and improve the animals’ genetic health, preventing the local extinction of the species.

Ethical and ecological considerations of genetic engineering in conservation

Although genetic technologies offer great advantages for conservation, they also raise important ethical and ecological questions that must be carefully evaluated. One of the main challenges is avoiding unintended consequences of genetic modification. Altering a species’ DNA can produce side effects that cannot be predicted, potentially disrupting the balance of ecosystems where the species interacts.

Another aspect to consider is the possible loss of natural genetic diversity. While genetic engineering can help improve the diversity of small populations, it should never replace traditional conservation efforts aimed at protecting natural habitats and species’ ecological interactions. Furthermore, genetic engineering practices must ensure animal welfare and minimize the suffering of organisms involved in experiments, such as cloning or IVF techniques.

Finally, genetic engineering should not be seen as a standalone solution, but rather as a complement to traditional conservation strategies. The protection of natural habitats and the reduction of harmful human activities remain essential to ensuring the long-term survival of species.
