14 of carbon released into the Earth's atmosphere, the fluctuating cycle found a balance after the glaciers stopped melting.8 Although the Earth’s atmosphere had endured fluctuation in its climate from the melting glaciers, this time period resulted in an improvement of climate compared to what it was before. The Pleistocene Epoch and Wisconsin Glaciation provided inhabitable land with a new ecosystem, an abundance of natural resources, and an improved climate. The melting glaciers caused abrupt changes to the environment, however, the loss in habitat and population would be recovered with the nurturing of the once frozen land. This brings the opportunity for new plants and animals to thrive here. Along with the increasing temperatures, the melting glaciers would distribute the resources throughout the land because of the natural resources buried within the glaciers. Materials such as silt, gravel, and sand were distributed to form the base of the Earth’s topsoil. With coal, zinc, and other minerals found throughout the sediment. Followed with the recovery of soil being beneficial for habitation and its reduced risk against erosion. These geological changes have improved the climate through the melting of glaciers. The levels of greenhouse gases, like carbon, which have been released into the atmosphere have caused fluctuating changes to the climate until the rising temperature had found a balanced with the amount of carbon being released. Thus, creating the atmosphere that is present today. The changes the Pleistocene Epochs endured involved severe risks in order to achieve what is present now. It is arguable that this epoch only caused destruction because of the amount of habitual and animal loss. Yet, with loss, there had been a gain in improvement for both the health of the land, and for the opportunity for new plants and animals to thrive in this bioregion. 8 Pyne, Lydia V., and Stephen J.
