According to the biologists, humans play an important role in the extinction of animals, globally. The scientists have conducted a study and prepared a data on numbers of animals which disappeared from the earth. As per this data, two vertebrate species go extinct every year on average, but very few people notice this.
Because of the slow decreasing rate in the animal species very few people notice the present threat to the natural systems we rely on. The scientists conducted this study while keeping the global evaluation of these population trends in mind. The scientists stated that this study shades the lights on trends of extreme decline in animals’ population.
The biologists also added that the newly accumulated data is a result of a biological extermination occurring globally, even if the species of these populations belong to, are still present somewhere on Earth.Earlier, scientists had presented a study in 2015 where it was shown that Earth has entered an era of mass extinction unparalleled since the dinosaurs died out 66 million years ago.
As per the International Union for Conservation of Nature (IUCN), about 41 percent of all amphibian species and 26 percent of all mammals are included in the threatened and extinct species’ list.Various factors such as habitat loss, overexploitation, invasive organisms, pollution, toxification and climate change are key responsible aspects of this global disaster scene, stated the scientists.
