Carbon Dioxide
A carbon footprint is a measure of the impact human activities have on the environment in terns of the amount of greenhouse gases produced, measured in units of carbon dioxide.
There are a few human activities that would have a direct impact on the oxygen-carbon dioxide cycle. Planting trees and other plants is one of these activities.

Human activities can alter the atmosphere because of greenhouse gasses and aerosols. The greenhouse gasses that are released due to human activities include methane, nitrous oxide, halocarbons, and carbon dioxide.
Burning fossil fuels like coal, oil and natural gas, and deforestation, are the human activities. The first releases carbon dioxide, and the second means the trees are no longer able to absorb the carbon dioxide from the atmosphere.
The amount of CO2 in the atmosphere is increasingly drastically, attributed primarily to human activities.
