The man in this comic strip tells the man in the hat to not cut down the tree because the tree will protect them from having too much CO2 in the future. However, the man himself is contradicting his own statement, as he is adding onto the greenhouse effect. He uses his vehicle which is a major influence/issue to the amount of polluted air there is in the world, therefore, the man in the hat seems to be confused as to why the man in the car is worried about the greenhouse effect, when he himself is adding on to the amount of CO2 there is in the air.
