Back in 1995, the US Fish and Wildlife Service were looking for ways to revive the population of wolves in the Yellowstone National Park. Wolves have been extinct since 1926, but things were about to change in 1995 when the US Fish and Wildlife Service decided to release a pack of 14 wolves in that area. Little did they know, the wolves would change the entire ecosystem!
20. Pack of Wolves
The folks from the US Fish and Wildlife Services captured 14 wolves in Canada and took them in the Yellowstone National Park. Wolves have been extinct for nearly 70 years in that area and the new pack changed everything!
