Biogeochemical cycles are known to be coupled, meaning that all the different phases and cycles in the natural world (including the water cycle, the nitrogen cycle, and the carbon cycle) are conected to each other. All these different occurences happen in harmony with the other forces working around it. Especially with all things, such as global warming, affecting our atmosphere, it is important to study and further examine all aspects of the biogeochemical cycles and find a solution to the environmental issues. Tim Killeen, NSF assistant director for geosciences, says that, "Biogeochemical cycles don't exist in isolation..." It is crucial to understand that we have to study these cycles in terms of how they are harmonizing with the cycles around itself. This is a method that scientists can use to determine how humans have impacted the environment.
