An international team of scientists is warning that Earth may be entering the early stages of another mass extinction event, reports Live Science.
More than 320 land vertebrates have gone extinct since the year 1500 and many of the worldâ€™s plant and animal species are endangered, says a new study. Up to one-third of all vertebrates are threatened or endangered, the researchers said.
Large land animals, such as elephants, rhinoceroses and polar bears, show the highest rates of decline. They are at particular risk because they tend to have few offspring and low population growth rates. Hunters and poachers also find their fur, meat, tusks or horns to be attractive targets.
