Extinction is an inevitable phenomenon, according to The Daily Beast. Earth, our living planet, is on the verge of the sixth mass extinction.

Our planet has already experienced five major mass extinctions caused by methane, asteroids and volcanic eruptions. These include the Ordovician-Silurian, the Devonian event, the Permian extinction, the Triassic extinction, and the Cretaceous extinction.
Conservationists said that the growing evidence of extinction points to the guilty party — humans. Yes, it will be humans that are going to be responsible for the loss of his own race.
What are the basis?
Scientists found that human activities are accelerating this catastrophic event by 53 to 100 times than the natural rate. Researchers defined this kind of rate in the context of calculation that in every 100 years, two out of 10,000 species go extinct.
Over the past century, the expected species extinctions were only nine. However, 500 species have been discovered dead.
It doesn't make any sense. Why are human beings taking the fall?
Studies show that human population has been rising significantly, The Westside Story learned. This leads to an increase in the demand for lands to be used for farming and housing settlement, and this can only be met by destroying natural habitats.
Another factor contributing to extinction of species is the climate change. Although this is already an existing phenomenon, the increase of carbon emission in industrial factories contributes to its rapid change and global warming.
Toxins, which can alter the ecological system, are also considered as factors. Human activities such as deforestation and wide-scale fishing have contributed to this impending extinction.
Scientists refer to these "highly conservative" figures — pointing to the death of 69 mammals, 146 amphibians, 80 birds, and 24 reptiles in 1900 — as a global biomass crisis.
In British Columbia, more than 750 species are listed as threatened, endangered or extinct, CBC News reported.
Researchers set an estimated time line for the next extinction to be in 240 to 540 years. They have strongly suggested that the only way for this planet to be saved is by regulating the use of curb carbon, rehabilitating the natural habitats and altering the present farming practices.
