How do your household activities influence the cycle of carbon, nitrogen and phosphorus?

A flux is a flow—in this case, the flow of carbon, nitrogen, and phosphorus through your household (or through the vehicles or airplanes your household uses for transportation). Answer a few questions about who lives in your house, your diet, your yard maintenance habits, transportation patterns, trash disposal and recycling, and home energy use, and the calculator shows how much of those nutrients your household is using and emitting.

Carbon, nitrogen, and phosphorus are essential for all living organisms, but too much in one place can also contribute to air and water pollution. Reducing your inputs, where possible, will reduce your outputs, too. The choices you make at home can become part of the solution.
