Lessons > Feedback Effects > For Your Consideration
As you have seen in this lab, despite the natural tendency of the carbon cycle to regulate the amount of carbon in the atmosphere, the system is currently being overwhelmed by human fossil fuel combustion and deforestation. If this increase in atmospheric CO2 results in temperature rise as scientists predict, there are several possible factors that could cause feedback effects. If human beings are to mitigate these risks, they will have to take strong action soon.
In the Energy lab, you will explore the nature of some of the changes we could make in our global energy use and how these changes could affect our planet's delicate balance.
What are some viable ways of lessening the effect that increased carbon has on the following?
The carbon cycle is only one of many natural (and human "enhanced") cycles: hydrogen, water, nitrogen, and oxygen are some other cycles you may want to investigate. Think about how these cycles have changed due to human impact.
