paragraph_text: Disadvantages of de-extinction
  
  The reintroduction of extinct species could have a negative impact on existing species and their ecosystem. The extinct species' ecological niche may have been filled in its former habitat, thus making them an invasive species. This could lead to the extinction of other species due to competition for food or other competitive exclusion. It could also lead to the extinction of prey species if they have more predators in an environment that had few predators before the reintroduction of an extinct species. If a species has been extinct for a long period of time the environment they are introduced to could be wildly different from the one that they can survive in. The changes in the environment due to human development could mean that the species may not survive if reintroduced into that ecosystem. A species could also become extinct again after de-extinction if the reasons for its extinction are still a threat. The woolly mammoth might be hunted by poachers just like elephants for their ivory and could go extinct again if this were to happen. Or, if a species is reintroduced into an environment with disease for which it has no immunity, the reintroduced species could be wiped out by a disease that current species can survive.
  
  De-extinction is a very expensive process. Bringing back one species can cost millions of dollars. The money for de-extinction would most likely come from current conservation efforts. These efforts could be weakened if funding is taken from conservation and put into de-extinction. This would mean that critically endangered species would start to go extinct faster because there are no longer resources that are needed to maintain their populations. Also, since cloning techniques cannot perfectly replicate a species as it existed in the wild, the reintroduction of the species may not bring about positive environmental benefits. They may not have the same role in the food chain that they did before and therefore cannot restore damaged ecosystems.
  
  De-extinction also presents serious ethical challenges, particularly if applied to species high cognitive abilities such as Neanderthals. If such beings were recreated, they might possess capacities for suffering and self-awareness, raising difficult questions about their rights and moral status. Without clear legal protections, they risk being treated as research tools or experimental assets rather than sentient individuals.
