Each year, animals and plants are being lost to extinction. In fact, more than 160 species disappeared in the past decade alone. According to the World Wide Fund (WWF), the rapid loss of species we are seeing today is estimated to be between 1,000 and 10,000 times higher than the natural extinction rate. However, there have been some success stories over the years in which dedicated conservationists have been able to bring critically endangered animals back from the brink of extinction.
