The ship, which they also call the Ark of the 21st century, was inaugurated in 2008 and designed with the main function of protecting the world's crops from a global catastrophe to ensure that humans do not lack food. The bunker is buried 150 meters deep inside a mountain in the Arctic. Last year's extreme temperatures caused the permanently frozen layer to thaw, and water seeped into the vault and turned into ice when temperatures dropped again. This incident calls into question the capacity of the vault baptized by scientists as the most important room in the world , capable of preserving crops in the event of a disaster. On the other hand, most countries save key seeds for food production, the vault in Norway is the backup. The seeds are dried and frozen and it is estimated that they can be preserved for hundreds of years and, if necessary, can be used to regenerate crops. As Hega Njaa Aschim, spokesperson for the Norwegian government, which owns the establishment, explained to the BBC, the bunker was built in Svalbard because the permafrost was supposed to be permanent.
The problem was that in October 2016, when temperatures should have been around -10ºC, they reached 0ºC. "It was a very wet summer in Norway ," explained Aschim. Inside the mountain it is safe, but the problems we are experiencing are right outside and at the front of the tunnel , which is the entrance," Aschim said. "There may have been a change in the permafrost, but we don't know, and that's what Europe Cell Phone Number List climate scientists are now investigating," he added. The directors of the vault are taking safety measures, one of them is to build drainage channels to prevent water from accumulating in the access area, they also say that they will be able to waterproof walls as a precautionary measure . What they have already done is removed the electrical equipment inside the tunnel that gives off heat and installed air pumps in case a flood occurs in the future. These are the vaults where seeds from around the world are kept Likewise, Statsbygg, the agency that manages the bunker, will carry out a research project to monitor the state of permafrost in Svalbard.Due to climate change or illegal fishing , various species have disappeared. Recently, programs for the preservation of endangered species have been implemented and have contributed to the reduction of their disappearance.
Among these species, some are considered endemic, which means that their distribution is restricted to a certain territory and is also not found naturally in another part of the world. A clear example is the extinction in Mexico of 19 endemic species , such as the Guadalupe pinto toqui, the Guadalupe woodpecker, the San Benedicto rockhopper and the mustached sparrow, from Todos los Santos Island, in Baja California. Ajolote Another threatened species in Mexico is the axolotl, a salamander whose main characteristic is that it retains its larval traits throughout its adult life. The axolotl is an animal that has three ways of breathing: through the gills, the lungs and through the skin. It is proven that the axolotl loses a leg or even part of its eye, it can regenerate its body and become complete again. This species is an inhabitant that has been on earth for thousands of years, especially in the Valley of Mexico. He was worshiped by the Aztecs and is resisting death. According to the UNAM Institute of Biology, in 1998 for every square kilometer of the Xochimilco canal - an endemic place for these creatures - there were 6 thousand specimens ; between 2000 and 2004, they decreased to 1 thousand; in 2008 to 100 axolotls and to date it is estimated that only 30 of them remain.
