There are two questions.
1)The work you have completed in this module and the ones before it has shown you many examples of models and systems that can be explained in terms of positive and negative feedback. The discussion for this module asks you to reflect on these models and explain a system in terms of feedback.
* Provide an example of an issue in any context, i.e. environmental, social, educational, or financial (that has not yet been used in the course content or presented by your peers) and explain the factors contributing to the issue.
* Represent the issue within both the context of a negative feedback loop with a balanced outcome and in a positive feedback loop with an amplified outcome.
2)The climate of the earth is influenced by the amount of solar energy the earth receives and the composition of earths atmosphere. The earth has more carbon dioxide in its atmosphere now than it ever has during the existence of humans.

* Explain the reasons why the level of carbon dioxide in the atmosphere has increased dramatically in the past 150 years.
* The rise of carbon dioxide effects global temperatures and causes climate change. Climate for the most part has changed throughout the history of the earth, gradually over thousands of years, explain two consequences of rapid climate change to life on earth.
