Explain why humans cannot impact one of earth’s systems without impacting the others.

The activities of humans cannot impact one of the Earth's systems without influencing others. This is due to the fact that all the systems of the Earth are associated with each other. That is when one of the systems experiences even a slight change, the other systems, which are inter-associated will also get affected.  

As the systems of the Earth are connected with each other, they interact with each other by moving matter from one system to the other. The modifications made to the atmosphere due to the activities done by humans will ultimately result in the changes in the hydrosphere and biosphere.
