     The Contamination:

          Contamination is a very serious and delicate subject. This is because the human kind is the one responsible for it. The ecosystems and habitats were all stable until people started building machines that consumed the natural resources and destroyed the environment. A consequence of pollution is climate change. Climate change is when the greenhouse gasses are being produced or created in large quantities. These gasses accumulate in the atmosphere, trapping the Sun´s heat.

        Climate change affects everything. Example: a type of mountain hare changes fur color to blend in with its environment. During the summer/spring, its fur color is brown; during the winter, the coat changes to white. Because of climate change, the winter or summer arrives earlier or later than it is supposed to, this results in the hare changing fur color when the winter/summer hasn´t arrived yet, making them easier prey.
