Carbon dioxide makes a lair in the atmosphere that stop the sun heat going out. There are huge numbers of cars run on patrol and produce from it is carbon dioxide. Other type of transpiration like airplane and ships also produce carbon dioxide because they use another type of fuel like diesel for ships and kerosene for airplane.
