Question

DentroTest · Accepted Answer

Carbon dioxide (CO2) is the main gas responsible for the greenhouse effect and global warming. Although it is not toxic to human health in open spaces (unlike carbon monoxide, which is poisonous), its accumulation in the atmosphere traps heat. To distinguish the options: Carbon dioxide (CO2): Causes the greenhouse effect. The amount emitted is proportional to fuel consumption. Carbon monoxide (CO): Is a toxic and dangerous gas that reduces the blood's ability to carry oxygen, but acts differently from greenhouse gases. Hydrocarbons: Are unburnt fuel residues that can cause respiratory problems and allergies.
