A Sixth Great Extinctionby | 03-08-2015 00:18 |

As a result of the mass degradation and destruction of natural habitats by humans, the word as we know it is experiencing a sixth great extinction of animal species .This is the result of the most conservative estimates .It means that, this extinction is like the one that wiped out dinosaurs. This is due to the fact that the rate of extinction is equal to 100 times higher in the 20th century as compared to what it would have been without human impact. Studies conducted previously have warned that species could become extinct at incredible speeds as a result of the large impact that humans are taking land for farming, construction and timber. Dr. Cellabos and Paul R. Ehlrich authored a study that warned of the population bomb of humanity and its impact. Dr.Ceballos said that the study employed knowledge of natural or so-called background extinction rates. He said that it was conservative because the study had only looked at those species that are declared extinct. Due to strict rules, this can take many years after the species had actually gone extinct. Previous work assumed that one specie goes extinct per10, 000 per 100 years. However, the new study raises this to two species. Authors have found that the modern rates of extinction are 8 to 100 times higher .This means that instead of 9 vertebrates going extinct since 1900, 477 vertebrates have gone extinct. However there is some opposition to this. According to the team responsible for the analysis, rapid, greatly intensified efforts are needed to stop or retard the flow of extinctions of species on the planet. It is only when these efforts are put in place both at an international and local level everywhere that the diverse species that inhabit our planet can be properly allowed to live. |
