Behind many science fiction movies, there are certain technological developments that could be applied to our daily lives, if we take the example of the film Jurasic Park, would discover what so important or dangerous could be genetic engineering. Engineering through genetics and cryopreservation method are created again dinosaurs so powerful and deadly as the famous Tyranosaurus rex; Unfortunately this experiment with financial purposes out of control and everything becomes a hopeless chaos. On many occasions we have surprised us by the idea of being able to preserve life through the use of low temperatures; low temperatures have been used for many years in research labs to preserve cells or microorganisms as a bank or biological reserve, these cells or microorganisms conservarian its physiological properties for many decades, turning them into viable material for future experiments. This process is known as cryopreservation, and It is to suspend or preserve matter live at very low temperatures, matter or crops, if not so be deteriorarian quickly. The idea of cryopreservation is possible today thanks to the high technology in the field of equipment and instruments used for freezing and rapid acquisition of chemicals used with this purpose as the liquid nitrogen. Another advantage of cryopreservation is the important ecological application that might be; is that this process has the potential to become a tool of conservation at large scale, and when I refer to large scale I am referring to the possibility of being able to freeze or keep frozen an entire Zoo. And what is even more curious of this process is the ability to freeze species that are at a high risk of disappearing because of climate change, loss of ecosystems or disease; species in via of extinction would be the first beneficiaries of the advantages granted by the technology of the cryopreservation. The Bank of frozen species should form an important section in all the zoos in the world, a bank in charge of preserving reproductive cells, animal tissue samples or even fetuses and if it is possible to investigate the different cellular changes that occur at low temperatures, as well as the opportunity to study the comparative genetics of relatively nearby animals in the evolutionary scheme (Alisa OparPlenty Magazine: Issue 17; F.
