Body Climate change Human activities are considered to be contributing to an increase in average global temperature (Shah, 2012). First, human activities in general release carbon dioxide into the atmosphere. This seems not to be a problem because people think that plants will absorb carbon dioxide and produce oxygen to clean the atmosphere as “a carbon cycle”. However, the problem here is that people are exhausting far beyond the capacity of the environment.
