The world is filled with all kinds of mammals, birds, insects, reptiles, amphibians, and fish. There are over one and a half million species already described and documented and believed that there are even more still undocumented today (“Fact Monster Science” 2014). As much as our amazing world offers us, we humans are taking away as well. It is believed that 99.9% of species are now extinct; many of those that occurred over the last 25,000 years can be attributed to humans (“Foundational Concepts”2014). Humans have caused severe environmental changes such as global warming, loss of environment, animal trafficking, pollution of toxic chemicals and trash, and poaching. It’s estimated that 905 species are extinct and 16,928 are listed as…show more content…
Can we really reintroduce species back into the wild, when their habitat might be gone? Do they still have the survival instinct? The difference between de-extinction and reintroduction is de-extinction uses genes and DNA from extinct species and places them into in species similar to the extinct species and using cloning or selective breeding to revive the extinct species. Reintroduction is defined as releasing a species into an area in which it had been indigenous but has since become extinct (Jørgensen et al. 2013). The first use of reintroduction was in 1832. Western capercaillie was a bird found in Scotland, but by the eighteenth century, the bird’s population was dropping dramatically to the point where it had gone extinct due to habitat loss and poaching for meat and beautiful feathers. The Western capercaillie was first attempted to be brought back by using a cousin of the bird from Sweden, and raising these chicks by hand and cross breeding between these cousins and a few Western capercaillie (Jørgensen et al. 2013). From these small beginnings, the science of reintroduction was launched and became a full force over the last 30 years. Reintroduction was then established as a founded science by the International Union for Conservation of Nature (IUCN) and in its Species Survival Commission reintroduction specialist group, founded in 1988 (Jørgensen et al. 2013). IUCN guidelines directed background studies for identification, review of lessons learned from
