It’s no secret that many of the world’s animals are in danger of extinction – but most people would be surprised at just how small the numbers of certain species have become. One such example is the Mexican Gray Wolf. Current estimates count these wild wanderers at just 52 free-ranging wolves in the southwestern United States. With such a small population, each individual wolf and wolf pack is critical to the population's long-term survival.

The regal Black Rhino is a rare species these days. Extinct in some parts of the world, recent efforts to save this colossal creature are beginning to show promise in others. Black Rhino populations in Zimbabwe have recovered from a low point of only 370 in 1993 to around 500 animals today. It’s a slow process - but one well worthwhile.
