Lions, these wonderful big cats — I think there isn’t anybody who has ever avoided their charm — could be extinct in just 15 years. Even though they are dangerous, they are lovable, too. But, unfortunately, there’s some really bad news: their numbers have been shrinking tremendously over the last 50 years! While, in 1960, there were a healthy 450,000 lions in wild, in 2010, were only 20,000! If that trend continued, lions would become extinct in just just over 10 years.
