The Goal
The entire purpose of the experiment was to provide some tangible information to climate change deniers. Kurtis' point was simple. Plants are necessary for humans to survive and the more CO2 that humans pump out and the more plant life humans wipe out, the less oxygen is produced to combat the CO2, which is extremely harmful to humans in large quantities. So, he believed that the plants in his greenhouse would convert his CO2 into oxygen for him, and the cycle would continue throughout the duration of his experiment.
