The fight to prevent the extinction of species continues to take hopeful steps thanks to science. Cases like that of the northern white rhinoceros demonstrate that, even though the situation may be critical, recovery is possible with technology and human effort.
With only two surviving females in the world, the northern white rhinoceros seemed doomed to disappear. However, scientific advances such as in vitro fertilization have become fundamental tools for the species’ preservation. Thanks to the work of the BioRescue Project team, led by Thomas Hildebrandt, 33 viable embryos were created from genetic material of two different males. “The quality of the embryos is excellent, these are really encouraging news,” affirmed Hildebrandt.
This species conservation plan includes using surrogate mothers from a close subspecies, opening new possibilities to save this emblematic species.
## Successful Recoveries: Examples of Hope
However, the case of the [white rhinoceros](https://noticiasambientales.com/animales/murio-toby-el-rinoceronte-blanco-mas-viejo-del-mundo/) is not the only one, as there are others like the Iberian lynx and the Atlas lion that demonstrate the recovery of endangered species is not a utopia:
– **Iberian Lynx**: In 2002, there were less than 100 individuals left, but thanks to captive breeding programs and reintroduction into nature, the population exceeded 2,000 individuals in 2024, marking a milestone in the conservation of this species.
– **Atlas Lion**: Considered extinct a century ago, it has been brought back to life thanks to captive breeding. Specimens like Azghar, a cub born in the Rabat zoo, are proof that this species can reclaim its place in ecosystems.
## Other Challenges in Conservation
Despite the successes, many species still face serious risks:
– **European Mink**: With only 142 remaining individuals, this small mammal is critically endangered. In Spain, the La Rioja breeding center represents a new hope for its conservation, although the challenges of captive reproduction are considerable.
– **Siamese Crocodile**: A species once considered extinct showed signs of recovery with the discovery of a litter in Cambodia, an event that renews expectations for this rare species.
– **Giant Panda**: Although less critical, the birth of two cubs at the Hong Kong zoo highlights the ongoing global effort to preserve this emblematic species.
Advances in biotechnology, captive breeding, and habitat conservation are changing the narrative for many species on the brink of extinction. Although the road is long and challenging, the example of the northern white rhinoceros, the Iberian lynx, and other species shows that extinction is not always an inevitable fate. With will and resources, humanity can bring life back to ecosystems and preserve the planet’s biodiversity.
## The Importance of Preserving Species
Preserving species is important for the following reasons:
– **Biodiversity**: Biodiversity is an indicator of life’s health on Earth. A diverse and rich environment is more sustainable and provides life and prosperity to humans, animals, and plants.
– **Social Well-being**: Biodiversity is the basis of many environmental goods and services that contribute to social well-being.
– **Climate Crisis**: Wildlife conservation helps combat the climate crisis.
– **Ecological Barrier**: Conservation of ecosystems and wildlife acts as an ecological barrier to prevent diseases from spreading to humans and domestic animals.
– **Enrichment of Life**: Species enrich life with their colors, shapes, textures, scents, and behaviors.
– **Cultural Heritage**: Conservation allows access to the past and enjoyment of a great cultural heritage.
Human action is threatening biodiversity, and species are disappearing at a rate up to 1000 times faster than natural. To protect biodiversity, exotic species should not be acquired or abandoned, sustainable use of natural resources should be promoted, and altered ecosystems should be restored.
