Scientists warn about mass extinction of wildlife, 500 species endangered
The sixth mass extinction of wildlife on earth is fast approaching, according to scientists. More than 500 species like Sumatran Rhino, Clari├│n Wren, Espa├▒ola Giant Tortoise, and Harlequin Frog have less than 1,000 individuals left. They are likely to extinct in the next 20 years. This rate of loss would have taken thousands of years without human intervention, scientists said.
