Human Impact on Earth's Sustainable Cycles
By: Robert Faison
How does a class being conducted online instead of on campus increase or decrease the classes' contribution to the carbon cycle during the term?
Conducting online classes not only is time efficient but also prevents students to pollute earth. Being on campus would ask student for transportation. How will the students come from home to campus? Universities are never on walking distances therefor having a personal car or using transits such as buses or taxis is the only way to get to school. Universities hold thousands of students which mean if each student carried a personal car or used the transit that …show more content…
Action | Increase atmospheric Nitrogen | Decrease atmospheric Nitrogen | Fertilizer for agricultural fields | | Potent greenhouse gasReaches the stratosphere where sunlight breaks it into nitric oxide, a key link in the chain of reactions that damages the Earth’s protective ozone layer. | Transportation | | Ozone, Smog, Particulates, Acid rainSee chart below | Septic tanks | | A release of large amounts of nitrogen into the environment by discharging through a drain field into the ground. Microbial activity consumes the nitrogen and other contaminants in the wastewater. | Ammonium aerosols | | It is a reactant in the atmosphere, where it acts as an aerosol, decreasing air quality and clinging to water droplets, eventually resulting in nitric acid (HNO3) that produces acid rain. Atmospheric ammonia and nitric acid damage respiratory systems. |
