Did you know that likes animals, the environment evolves too through processes of natural succession. In the United States, there was a humongous ice sheet known as the Laurentide Ice sheet. This was around 2,600,00 to 11,700 years ago.This was a remarkable glacier because it was 3.2KM thick, and covered most of canada and northern Unites States. 

As it moved down due to global temperature changes, it melted and carved the face of most of the United States. It scraped into the ground forming kettle holes, drumlins, eskers, and glacial moraines. Later on when the ice melted, the areas that had land scraped on them and instead had pieces of the glacier, became lakes and many cities were built around it.

This is remarkable because today, one can still find remains of the glacier boulder in connecticut. Some are small smooth round shaped rocks that and others are huge towering boulders. In Hammonasset, we studied some of this huge rocks which were glacier at one point. They were mixed with silt and deposits and hence in many rocks, you can find gold or precious metal deposits. 

This is an example of how like the environment is shaped by events in history and the long term effects of this can be seen. This also suggests that today, if we continue to destroy our Earth, the effects may have lasting and more devastating impact than any of us can imagine. On the brighter note, change and shifts in the environment should not always be viewed as a negative thing. The Laurentide ice sheet may have reshaped the visual face of Northern America but it developed new features which aided humans.
