Rhinos are at once some of the world’s most popular animals, and some of its most critically endangered. These massive animals require plenty of space, and destruction of their habitats has put them at great risk. On top of that, poachers hunt rhinos for their ivory horns, to the point that some species of rhino are on the brink of extinction.  There are only three northern white rhinos remaining in the world, and only sixty or so Javanese rhinos.

However, all hope’s not lost—environmental scientists have been working to preserve these amazing animals, and have had some success. The southern white rhinoceros nearly went extinct, but there are now over 20,000 individuals, thanks to conservation efforts to protect them from poachers and reintroduce them to areas where they once lived.
