Although; bringing back these animals to these places where they once roam is key to help reduce warming up our planet. Although; bringing back these animals is important because, we need these animals to keep the frozen ground in check. Despite having a successful campaign to add more animals to their park in Russia, this is key for these animals to be introduced, and establish themselves overtime. Well, having at least 2000 deer will be a possible number what I am predicting when plans are successful. However; having bison, horses, and muskoxen are also important. Typically, few animals is a typical start, and it may take years for established numbers to grow. It may also take time for Pleistocene Park to have more animals to emulate pleistocene conditions. Well, we are also from a pleistocene era, and we must reconsider cooling down our planet,and reduce air pollution.
