Compose four paragraphs in which you:
*briefly describe a biogeochemical cycle or nutrient flow of your choice,
*explain at least one way that humans impact this flow and why this is important to the health of humans or other life forms; and
*reflect on at least one measure to improve our impact (either as individuals or as a society). If other people have already presented substantive posts on a given cycle, you might consider treating a different cycle.
To prepare for this Discussion
Select a particular nutrient flow or biogeochemical cycle to focus on in your primary research-based post this week. Consider some of the benefits or services provided by this natural flow or cycle.
Consider the ways that humans impact the cycle of flow of your choice and how this impact challenges the health of humans and other life forms.
Reflect on what can be done to improve or mitigate our impact either individually or as a society.
