There are about 1.5 x 109 scrap tires in the world at the moment; this represents a major waste disposal problem. a. If all of these tires were burned with complete efficiency, by how much (in tonnes) would Earth''s current atmospheric load of C02 increase? b. Compare this to the current atmospheric C02 load. Assume rubber has a molecular formula of C200H400 and that each scrap tire weighs 8 kg, has a diameter of 48 cm, and is 85% rubber.
