Humans
Due to humans living mainly at sea level where the atmospheric pressure is about 30% higher than at high altitude the change in altitude can effect us greatly and lead to altitude sickness.
This can cause many problems in our bodies although we have developed some coping mechanisms in order to try and cope with such a change in our environment.
